Steps to reproduce

Install Mageia 8 RC1 32 bit, nemo crashes

Expected behaviour

Other information

Also any ideas on how to debug or any candidate fixes would be useful. This is a release blocker for Mageia 8.

Need a trace

Does it run if you disable the sidebar?

gsettings set org.nemo.window-state start-with-sidebar false

Can't you add this to the spec file?

ExcludeArch:  i586 i686

Don't expect any fixes from upstream as we don't really support 32bit any more as we don't have any 32bit installation media in our distro's.

[mtwebster]

Do you have an iso I could try?

gsettings set org.nemo.window-state start-with-sidebar false

for me this fixes the crash.

I have lot of errors in the terminal but it starts :-)

Btw this is not a 32bit error as i am running a Mageia 8 64 bit and encounter this issue.

[neoclust]

how can i provide a useful trace for you ?

[mtwebster]

I would presume these steps would work: https://wiki.mageia.org/en/Debugging_software_crashes

You need debug packages for xapp, nemo, gtk3, glib2

Once you have these you could run:

gdb nemo
r

when it crashes, do:

set pagination off
thread apply all bt

And paste/pastebin the output. Please paste the entire output from when you first run gdb nemo - you mention a lot of errors/warnings, I'd like to see them. I'm not entirely convinced this isn't some build config or other issue - the logs should be reasonably quiet and we've had no similar reports on any other distros.

Thanks

Also something that would be useful is to run nemo under valgrind

Might be related to #2579

I've just pushed this: https://github.com/linuxmint/nemo/commit/fbf57e72e9c4fc3fbded6cd23b682c35619ee4c3

Lacking any more info, this is a bit of a shot in the dark, but this is a more explicit way of accomplishing our check here, and safer. Not sure if someone can cherry-pick that to test? I'll try to get a new tag on nemo (for other fixes as well).

[joequant]

Okay. Let me create a test rpm for mageia with all of the latest fixes.
