Solus segmentation fault

[Raymonf]

Hi!

I'm trying to use ibus-rime on Solus OS, and when I switch to Rime with ibus-daemon, this shows:

(ibus-ui-gtk3:3112): IBUS-WARNING **: ibus_bus_call_sync: org.freedesktop.IBus.SetGlobalEngine: GDBus.Error:org.freedesktop.DBus.Error.Failed: Set global engine failed: The connection is closed

(ibus-ui-gtk3:3112): IBUS-WARNING **: panel.vala:817: Switch engine to rime failed.

Upon debugging /usr/lib/ibus-rime/ibus-engine-rime in gdb, this is revealed:

Program received signal SIGSEGV, Segmentation fault.
0x00007ffff374071a in std::ostream::sentry::sentry(std::ostream&) ()
   from /usr/lib64/libstdc++.so.6

Any ideas? Thanks.

Need more information. Can you please post the full stack trace? i.e. the output by typing bt at the gdb breakpoint.

[Raymonf]

Oh, that's how you show it. I was looking for that!

It appears to have crashed when writing logs to /tmp/rime.ibus.*. Is there anything special about the /tmp directory on the system?

[Raymonf]

I'm not completely sure. As a normal user, I can touch files in /tmp/, as well as write to and delete them.

Also, this happens with rime_deployer as well, so I had to manually put brise data, which I compiled on another system, in /usr/share/brise:

Whoops, I'm an idiot. I used the latest version of glog instead of what was bundled (in thirdparty/src) since I didn't know it was there.

Works now. Perhaps put it into the docs?
