<br>
but this is of limited usefulness since you don't have debug symbols for<br>
mutter available.<br>
<br>
The easiest way to get the debug symbols is to use:<br>
<br>
DEBUGINFOD_URLS="<a href="https://debuginfod.debian.net" rel="noreferrer" target="_blank">https://debuginfod.debian.net</a>" coredumpctl gdb<br>
<br>
and type "bt" at the (gdb) prompt when the symbols have finished<br>
downloading.<br>
<br>
Or you could enable the debug symbols apt repository (see<br>
<a href="https://wiki.debian.org/HowToGetABacktrace#Installing_the_debugging_symbols" rel="noreferrer" target="_blank">https://wiki.debian.org/HowToGetABacktrace#Installing_the_debugging_symbols</a>)<br>
and install the libmutter-12-0-dbgsym package. We don't need any other<br>
packages for this particular crash.<br>

<br>
In general we can't get a useful backtrace from the actual compressed<br>
core dump: that's something that the bug reporter needs to do. I tried to<br>
get a useful backtrace from this with debug symbols, but it doesn't match<br>
the result you sent and I'm not sure whether it really makes sense.<br>
<br>
Sharing these core dumps is also a privacy risk because they can contain<br>
private information, although in this case the crash was from the gdm<br>
login screen before you had a chance to enter any passwords, so it's<br>
probably harmless.<br>
