Hello Nenad Cvetkovic,
I tried to have a look at your core file.
It shows a crash with following backtrace [1].
The reason seems to be an invalid function pointer in variable "prepare".
The upstream issue in [2] shows a similar backtrace, but I
am not sure if they are related about what is causing it.
Investigation with a core file needs the same installed
package version, therefore the inspection at the host
creating the core has less chances for discrepancies.
Therefore, if you have gdb installed, you should be able
to generate a backtrace on your system too by e.g.:
coredumpctl list
coredumpctl gdb <PID>
bt
This gets normally improved by installing the dbgsym packages
or setting the environment DEBUGINFOD_URLS,
both and more described in [3].
Therefore the question, is there a reason for what looks like
local rebuilt packages libenchant1c2a and libxml2
due to the "~1.gbp73138d" version postfix?
Kind regards,
Bernhard
