[matthiasclasen]

This stacktrace is sadly missing the interesting part:

 #5  0x00007ff230f7aa3c in gtk_message_dialog_new () at /lib/x86_64-linux-gnu/libgtk-3.so.0
 #6  0x000055884fcfd645 in  ()
 #7  0x000055884fcee168 in  ()

would be good to know where gtk_message_dialog_new is getting called

[Esokrates]

@matthiasclasen I'll try to find the memory dump, any idea how I could find out that info? Is this due to missing debugsymbol info?
