Sadly the hildon app-manager tries to be smarted than it really is. At least in one possible scenario the problem is caused by it's reluctance to update PyQt in a reasonable manner. An another source of confusion is that some packages incorrectly depend on the 'common' package (like peqersi), which they shouldn't. Considering the brain-deadness of HAM, it seems the only long-term solution is to depend on python2.5-qt4 (yes, I know I used to advise against that, but since Qt is optified nowadays and HAM does break if you depend on the components... there is no real alternative).

EDIT: But that seems not to be the root cause, see http://forums.internettablettalk.com...08&postcount=8
