Segfaults and corresponding questions!

Passing request on to the larger population :)

Hey there! In theory the TCP backend should be excitingly close,
however, whenever I clicked "OK" to add the account, I'm getting a
segfault. I've tried passing different datatypes, making the data a
member of the object instead of a local variable, and so on, and I
haven't had any success. Here's the backtrace - is there a clue I'm
missing? (In a non-debug build, not in GDB, it just closes the dialog
without adding any account.)

(BTW - every time I start Abi in GDB with a debug build, I get several
segfaults - I can just "continue" through them but I'd be curious to
find out what is the deal and if they in fact affect production builds.
I had these before, and removing AbiGrammar just shifted it to the next
plugin, IIRC. I did file a bug, I think. Looks like "lab()" keep
showing up

Weird, huh?)

Thanks for your help!
