claws --debug + gdb 7.6 trace

Caught another crash due to memory corruption while receiving messages (without
UI interaction). I keep the core file untouched in case someone needs specific
info.

I do not see, if this is a problem in claws or the used libraries.
Who knows why gdb throws around with dwarfs and what hit my memory this hard
that all traces are broken (see attached log).

Error in `/usr/bin/claws-mail': double free or corruption (out): 0x0c198a48
