If it is crashing we need a backtrace https://community.kde.org/Guidelines_and_HOWTOs/Debugging/How_to_create_useful_crash_reports#Backtraces (In reply to Albert Astals Cid from comment #1) > If it is crashing we need a backtrace > > https://community.kde.org/Guidelines_and_HOWTOs/Debugging/ > How_to_create_useful_crash_reports#Backtraces Hello Albert, sorry for the inconvenience. I just installed gdb by following the (K)Ubuntu guidelines. When I try to run Okular in gdb, it can go any further as there is a "warning: could not find '.gnu_debugaltlink' file for /lib/x86_64-linux-gnu/libcap.so.2 cannot fstatat canonical snap directory: Permission denied". I set environment variable for all user Can you help me please ?

HEre the answer should be probably yes.
Anyhow it seems you are using Okular from a snap? I have no idea how to debug that or if it can be debugged. I'll ping some people that maybe can help.
Hello, >>Enable debuginfod for this session? (y or [n]) n >HEre the answer should be probably yes. Ok, I tried but I always got the "cannot fstatat canonical snap directory: Permission denied" >Anyhow it seems you are using Okular from a snap?

BR, Pascal I have been pointed to https://snapcraft.io/docs/using-gdb-gdbserver Not sure it helps, my suggestion would be to not use okular packaged from snap, it always seem to bring problems. Pascal, I tested the exact thing, exact way that you shared to reproduce the bug. I tested it with the revision 265. The color changed perfectly. So, I'd request some debugging info from you. Please share the output of these commands snap info okular snap connections okular After these, run this command snap run okular And give the complete output until okular crashes Hello Soumyadeep Ghosh, thanks a lot for your reply.

Hope there won't be another ! Thanks a lot for your help. Not the fix I was aiming for, very difficult to fix a bug I cannot reproduce, so sorry, glad flatpak works for you. Cheers, Scarlett |
