Package: libglib2.0-0
Version: 2.58.3-2+deb10u1
Severity: important
File: libglib-2.0.so.0

Dear Maintainer,

I'm not sure but I think this happens since I upgraded to Buster on
2019-07-19
taking libglib-2.0-0 from 2.50.3-2 to 2.58.3-2
This (or similar situations) come up when I run Pidgin for some time.
The logs
are filling and then I'm trying to connect to another IRC server.
Final GDB backtrace attached but before that I already sent some bug
reports
to Pidgin's trac system:
https://developer.pidgin.im/ticket/17408
https://developer.pidgin.im/ticket/17410
https://developer.pidgin.im/ticket/17411

The first was answered and said it was a problem with libglib so I should
report here.
I updated from 2.58.3-2 to 2.58.3-2+deb10u1 which didn't correct the
problem.
This only changed the gdb output a bit. Unfortunately there's no newer
version
of libglib2.0-0

I would be happy if this problem was solved. Tell me if I should/can/if
it is
advisable to downgrade libglib-2.0-0

TIA
