Comment 94 for bug 1782984

I would like to add some info that may help to narrow the problem.
I have had this crash in PCManFM since i upgraded ubuntu from 16.04 to 18.04 but the same bug manifest in Geany and Chromium as well. The bug could hit PCManFM within a few clicks opening directories and then clicking on a file or can take hours to show up. In the case of Chromium it usually hit at the launch of the browser.

I rebuilt the LibX11 with the supposedly fix mentioned by Tycho Kircher and apparently this has not fixed the problem but the crash is now without the Assertion `!xcb_xlib_threads_sequence_lost' failed.

I installed only these packages:

* libx11-xcb1_1.6.4-3ubuntu0.2_amd64.deb
* libx11-xcb-dev_1.6.4-3ubuntu0.2_amd64.deb
