--- Comment #4 from Rafał Mużyło galtgendo@o2.pl --- So, as I've mentioned on irc, recently gstreamer began to hang some of wine apps (that were running fine before) by running out of resources.
A hint by zf suggested those resources is actually address space.
That led me to an experiment: I've set large address aware bit on the executable in question.
Given that the hang was randomly triggered and took quite a bit of time, I can't be sure it *definitely* solved the problem, but for the time being it does seem so.
