--- Comment #73 from RJVB <rjvber...@gmail.com> --- This is probably not related but then again maybe it is: smb4k (git/head) has been crashing on me when quitting, with the backtrace below. In this case it looks like there is a bug in VLC 2.2.4 where certain libvorbis resources are freed twice, or attempts are made to free resources that were never allocated. Rather easy to prevent in VLC's function `Ogg_CleanSpecificData()`. I mention this here since double frees or null pointer dereference doesn't always lead to an immediate crash, but can lead to seemingly random events later on. Can we be certain that this longstanding ticket/bug has nothing to do with this Ogg issue? After all KDE uses .ogg files for audio notifications... ------------ Application: Smb4K (smb4k), signal: Segmentation fault Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
