Thanks Eike. But the backtrace didn't help. The crash is simply not possible at
that point, short of memory corruption.

The pointer that Nicolás posted actually corroborates that hypothesis: memory
smashing. Note how the pointer contains exactly 4 legal UTF-16 characters:
0x6f006900740061 (that is, the string "atio").

If this problem happens only when that string is sent, I recommend you do a
step-by-step debugging of the string decoding, to see where things went wrong.

Nothing here has proved a D-Bus error, nor even a Qt bug. If you can reduce it
to a Qt-only testcase, I'll take a look.
