I encountered similar problems with my program MovieSchedule: it fails on my N900 since installation of PR 1.3 and I got mails from 2 users which encountered problems also (but on of them sent a mail a little bit later that it works again). As the download number let me assume that MovieSchedule is used by more than 20.000 users I bet that it runs fine on most N900s with PR 1.3.

I found some problems with muti-threading and QNetwrokAccessManager (and opened Qt bugs which got classified as critical). Unfortunately I found work-arounds only for one of the two problems so I couldn't fix it yet.

I was thinking if I should do a fresh install of PR 1.3 to test if it runs fine then. I did an install OTA and had to remove some packages before so maybe the software files because of some conflict with other packages (though I have not installed a new kernel I installed a lot of packages from extras-development).

Do you know if the problems are related to fresh install or update of PR 1.3?
