It took me some time to get even only a 'nice' stack trace for the
X error within ishmail. At first one had to figure out the X error handler
that gets installed, waiting for exit() didn't help here ...
X Error of failed request: BadWindow (invalid Window parameter)
Major opcode of failed request: 18 (X_ChangeProperty)
Resource id in failed request: 0x0
Serial number of failed request: 88
Problem is "low-level" triggered by an early XtAppCreateShell ().
At least upon first glance the app is quite happy after neglecting the error

As written earlier(?) debugging here is no fun, since on linux i86 and alpha gdb like
to crash while debugging, and especially on alpha gdb tends to produce nonsense output
...
Also it's hard to 'follow' a C++ app through gdb. I tried even gdb 5.0 is there
something better than 's' to really go step by step (following all
constructors's calls, etc.)?
