Navit crashes after klicking Town search but only when GPS-USB receiver is connected and only with Reiseplaner Maps. With OSM Maps no crash. I use Marco Polo Reiseplaner 2007/2008 maps and have compiled a latest Version of Navit on Ubuntu 14.04 (trusty).

I'm afraid there are no currently active team members who has a copy of Marco Polo Reiseplaner 2007/2008 maps, so no recent changes were tested for compatibility with these maps.

Does it crash as soon as you enter into Town search dialogue, or only when you enter a letter (or a few letters)?

Does disconnecting the GPS-USB receiver prevent Navit from crashing? Do you have an active route at the time of crash? The does it crash if you press "Abort navigation" before entering Town search?

Try running Navit under valgrind or gdb, maybe this would help getting more informative stack trace.

Hi,

Q: Does it crash as soon as you enter into Town search dialogue, or only when you enter a letter (or a few letters)? A: It crashes as soon as I enter into Town search dialogue.

Q: Does disconnecting the GPS-USB receiver prevent Navit from crashing? A1: When disconnecting the GPS-USB receiver while Navit is running and then enter into town search it still crashes. When disconnecting the GPS-USB receiver before starting Navit it doesn't crash.

Q: Do you have an active route at the time of crash? The does it crash if you press "Abort navigation" before entering Town search? A: No difference if active route or not - always crashes.

Some output from gdb:

===========================================================

Hi,

did some more investigations:

My Mapset looks like this:

    <mapset enabled="yes">
        <map type="mg" enabled="yes" data=".../NAVIT/maps/DE.map"/>
        <map type="mg" enabled="yes" data=".../NAVIT/maps/DE.map/smp1.smp"/>
        <map type="mg" enabled="yes" data=".../NAVIT/maps/DE.map/smp2.smp"/>
        <map type="mg" enabled="yes" data=".../NAVIT/maps/DE.map/smp3.smp"/>
        <map type="mg" enabled="yes" data=".../NAVIT/maps/DE.map/smp4.smp"/>
        <map type="mg" enabled="yes" data=".../NAVIT/maps/DE.map/smp5.smp"/>
        <map type="textfile" enabled="yes" data=".../NAVIT/poi.txt"/>
    </mapset>

and it crashes with connected GPS-USB receiver.

When I remove just the line i.e. ..../smp3.smp where I am located at that moment it doesn't crash.

I took the liberty to edit your gdb trace for readability, hope you don't mind.

Out of curiosity, why do you prefer using Marco Polo Reiseplaner Maps? Those maps are badly outdated, and OSM is really detailed nowadays.

I probably have my M&G copy lying around somewhere if I can't find it, but I'm not sure it's worth the effort, unless you have a specific need.

Hi,

I would be happy if OSM maps would be usable but unfortunately there is a bug, not rendering large lakes correctly, the water area is not filled with blue color. See bug #754 Multipolygon relations not handled correctly.

So I keep using Reiseplaner Maps, old but working.

I found the problem of the crash in gui_internal_search.c

I commented out this and now it doesn't crash any more: / tracking=navit_get_tracking(this->nav); if (tracking && tracking_get_attr(tracking, attr_country_id, &search_attr, NULL)) country_attr=&search_attr; /

It is not the solution but a work around. So something in this lines of code must go wrong with Reiseplaner maps. One thing I noticed is that the attr_country_id is 131082 (must be Germany) and this ID is not in country.c

Hi!

Thank you for publishing the workaround you found. It has helped a lot in tracking the problem down.

I think this commit should fix it.

Please check if current unmodified code works well for you.

Hi,

unfortunately the fix doesn't solve the problem. It seems that only when using Reiseplaner Maps the code I commented out will be used at all. It seems to be a feature to set the current location country as starting country for the town search dialog. This country will be different from the default country when travelling outside the home country.

But I can live without this feature.

More important for me is to get the OSM bug fixed, (see bug #754 Multipolygon relations not handled correctly.) where the rendering of large lakes with blue color doesn't work. If this is fixed I then will switch to using OSM maps.
