First of all, I forgot to say I'm on Linux Debian, sorry @Martin for not mentioning!

Dear Christian,

I'm not sure if the "--enable-debug" flag changed the output of the first lines of the gdb backtrace in any way, please see below, to me they seem just the same...

Here's what I dit:

recompiled gwenhywfar:
I did not git pull, so we are as of Oct 14th.
$ export LANG="C"
$ ./configure --with-guis="gtk3" --enable-debug

also recompiled aqb and gnucash.

Then ran:
$ gdb gnucash
(gdb) run --debug --extra
Starting program: /usr/local/bin/gnucash --debug --extra
[Thread debugging using libthread_db enabled]
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
[ … here's some various gnucash startup debugging outputs … ]

Gnucash is open. Empty file. I enter the aqbanking wizard straight away, "edit" the only existing user, "get certificate", OK, "Get Bank Info", Crash.

Here's the first lines of the backtrace:

Thread 1 "gnucash" received signal SIGSEGV, Segmentation fault.

Please let me know if I can do anything else.
