The new build still has the same problems that are mentioned here: http://forum.parallels.com/showthread.php?t=2268 If you have the QT toolkit in /usr/local/Trolltech/ and you start Parallels you get an instant crash. This has been known by the Parallels team for months now. Could you please look into this now? This just can't be that hard to fix.
Alas this bug is still there in build 1898 ;( This was going to be fixed in Beta 3: http://forum.parallels.com/showthread.php?t=471 Parallels team, please acknowledge this bug or, even better yet, fix it
It should be fixed in build 1908 - check this topic please http://forum.parallels.com/thread4487.html.
Alas this build doesn't seem to improve things. It only works if I rename /usr/local/Trolltech to something else. Otherwise I get an instant crash when I try to start Parallels.
