Description a.mux 2018-05-11 16:52:28 UTC
Small workbook with some rows and a dispersion chart in it.

Immediately after becoming unresponsive, the following text was printed in the console:

[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.
soffice.bin: ../../src/xcb_io.c:259: poll_for_event: Assertion `!xcb_xlib_threads_sequence_lost' failed.

Steps to Reproduce:
Not easy to reproduce. Please find a link to the crash report.

Actual Results:  
Calc stopped responding. After some time Xorg proposed to kill the process.


Expected Results:
Calc should have worked normally

Reproducible: Didn't try

User Profile Reset: No

Comment 5 Timur 2020-11-27 18:59:56 UTC
There must be steps to reproduce. Please try to find. 
Until then this can only be Needinfo. 

You may click on crash link and see bugs with similar signature. This may be a duplicate, please see. 

Once there are steps, they need to be tested with daily master. 
Also, after steps are clear, please try User Profile Reset/Rename.

I am the original reporter of this bug.

At the time it happened frequently (to the point of being risky for the safety of one's data), but it was really hard to define a minimal case. My linux installs are normally well tidied up, so I suppose it could really have been some compatibility problem between LO and an official library from my distro.

After 2 years, every single library has changed on my system. I am currently on Ubuntu 20.04. On that OS, I have used Libroffice 6.4 (official debs from the website) for a long time with no recent crashes.

I recently moved on to d7547858d014d4cf69878db179d326fc3483e082 (still official debs) and from a quick test I am no longer able to cause a crash.

I think this bug can be safely closed, thank you.

As for Arvind, this signature has also other bugs - Unfortunately without steps.
