--- Comment #3 from ne4@parsoma.net 2008-08-05 15:10:50 --- (1) It happens even with a clean ~/.wine directory.
(2) My backtrace has filenames and line numbers. According to http://wiki.jswindle.com/index.php/Debugging_Wine#Understanding_and_reading_... that seems to be what a non-debug build misses, but what a default source build possesses. As it happens, the backtrace I posted comes from git on 2008-08-02, per my initial message. If you want a better backtrace, please be explicit in what manner.
(3) Reproducing this with the file posted requires reducing the horizontal window size substantially, probably to under 100 pixels or less. However, it happens reliably. Can you still not reproduce?
