Comment 2 Jonathan Thomas 2012-09-25 23:46:04 UTC
Buffer overflow in QProcess, nothing that can be done by Muon.
Comment 3 Christoph Feck 2012-09-26 01:22:29 UTC
QProcess doesn't overflow itself. The issue here is that some kded module leaks file descriptors. This doesn't mean the bug has to be in the muon module. See also bug 306908.
