Hello Alf Gaida, I am just looking through crashees of some random packages and stopped on this bug.
I found that you used at least following packages from experimental: evolution libglib2.0-0 libsoup2.4-1 And unfortunately there are no dbgsym packages for the versions of that time of libglib2.0-0 libsoup2.4-1 available on snapshot.debian.org. If the issue is still visible with current versions, you may add the following dbgsym packages like described in [1]: evolution-dbgsym libevolution-dbgsym libglib2.0-0-dbgsym libsoup2.4-1-dbgsym And create another backtrace. That should contain more function names and line information. If it is not an issue anymore the bug might be closed, I guess, by sending a mail to 933150-d...@bugs.debian.org Kind regards, Bernhard [1] https://wiki.debian.org/HowToGetABacktrace#Installing_the_debugging_symbols
