--- Comment #12 from Tobias Deiminger <haxti...@posteo.de> --- Ok, got it. It's this place in PresentationWidget::inhibitPowerManagement m_sleepInhibitCookie = reply.value().fileDescriptor(); We must not store QDBusUnixFileDescriptor::fileDescriptor, but clone it before. >From http://doc.qt.io/qt-5/qdbusunixfiledescriptor.html#fileDescriptor "It is ok to use it while this object is valid, but if one wants to store it for longer use, the file descriptor should be cloned using the Unix dup(2), dup2(2) or dup3(2) functions." Changing the code to m_sleepInhibitCookie = dup( reply.value().fileDescriptor() ); avoids crashing. Let me gather a bit more context to see if it's really that simple, then I'll send a patch at Phabricator. Maybe one can try and confirm the above code change in the meantime? -- You are receiving this mail because: You are watching all bug changes.
