OpenLP does not start on Arch Linux

[Andreas Preikschat]

Hello,

trunk r1857, arch linux

OpenLP does not start on Arch Linux, no exception is raised, but a segmentation fault.

Dependencies: http://pastebin.com/cLsqwBr7

Here is the command line:

[andreas@andypc trunk]$ python2 openlp.pyw -l debug -d
Logging to: /home/andreas/.openlp/openlp.log
WARNING: bool Phonon::FactoryPrivate::createBackend() phonon backend plugin could not be loaded

Warning: -accept=pipe,name=openlp_pipe;urp; is deprecated. Use --accept=pipe,name=openlp_pipe;urp; instead.

I analysed the problem and it lies in the impresscontroller, in the start_process method:

            cmd = get_uno_command()
            self.process = QtCore.QProcess()
            self.process.startDetached(cmd)
            self.process.waitForStarted()

If I uncomment the waitForStarted call then openlp starts fine.
