[Touch-packages] [Bug 1782984] Re: PCManFM freezes with Assertion `!xcb_xlib_threads_sequence_lost' failed when clicking on a file or folder in 18.04

It is random and difficult to provide clear steps to reproduce. It is, however, a common situation. EXPECTED RESULTS pcmanfm works without problem. ACTUAL RESULTS == All pcmanfm windows become unresponsive, though background processes (e.g. copying) may continue without problem. with the same error message in ~/.cache/lxsession/LXDE/run.log: [xcb] Unknown sequence number while processing queue [xcb] Most likely this is a multi-threaded client and XInitThreads has not been called [xcb] Aborting, sorry about that. pcmanfm: xcb_io.c:259: poll_for_event: Assertion `!xcb_xlib_threads_sequence_lost' failed. ** Message: 19:58:49.267: app.vala:130: pcmanfm exit with this type of exit: 6 ** Message: 19:58:49.268: app.vala:148: Exit not normal, try to reload (note the timestamp on the message will vary) AFFECTED VERSIONS = 1.2.5-3ubuntu1 NOT 1.2.4-1ubuntu0.1 UPSTREAM BUG https://sourceforge.net/p/pcmanfm/bugs/1089/ ADDITIONAL NOTES Other GTK2 file managers (e.g. Thunar) and applications (e.g. GIMP, Leafpad) seem to have the same problems. This is probably at least rooted in a GTK2 bug: https://bugs.launchpad.net/ubuntu/+source/gtk+2.0/+bug/1808710 To further assert this, note that there is a SpaceFM file manager that is available in GTK2 and GTK3. The GTK2 version displays the behavior. The GTK3 version does not. Same with LibreOffice.

[Touch-packages] [Bug 1808710] Re: !xcb_xlib_threads_sequence_lost error with GTK2 applications
Apparently it's a bug in libx11, which persisted for a long time but became much more likely with an update in libxcb.
