I analyzed the problem a bit more. I use the extension "ThunderBirthDay"
which creates a calendar with the birthday dates found in my address book.

If there is such a calendar, icedove crashes at startup. If there is no
such calendar, icedove starts normally.

Even with all extensions, plugins and language packs disabled icedove
still crashes when I want to open about:config. With all my extensions
and the two german language packs for icedove and iceowl-extension
enabled, icedove also crashes when I want to open about:config.

Only in safe mode icedove does neither crash at startup nor when opening
about:config.

Attached are the full logs I got with gdb for the two cases when icedove
crashes. Both times all extensions and language packs were enabled.

If I can give you more information, e.g. file system activity or
anything else, tell me.
