Comment 1 Marc 2012-08-02 10:19:33 UTC 
crashes in debug build only, on Q_ASSERT(ready) in DvbLinuxDevice::setDeviceEnabled when frontend could not be opened.
Doesn't crash on Release build.
Comment 2 Christoph Pfister 2012-08-02 11:24:05 UTC 
absolutely no reason to close this bug!
Comment 3 Marc 2012-08-03 11:58:55 UTC 
here's a fix for this crash. if the device has not been properly sarted (not "ready = true") then there's no need to stop it. Other calls to DvbLinuxDevice::stopDevice() do check if the device is "ready = true".

in dvbdevice_linux.cpp.

DvbLinuxDevice::~DvbLinuxDevice()
{
	if ( ready )
		stopDevice();
}
Comment 4 Mauro Carvalho Chehab 2016-06-01 11:09:24 UTC 
The Kaffeine version you're using is too old. We just released upstream a version 2.0.1, with is based on KDE5, and changed both the DVB and video play backends.

There, it has a stopDevice() at the DvbLinuxDevice() destructor, so it should be addressing this issue.

Could you please test the upstream version and see if it works? The README file contains instructions about how to compile it. You can find it at our git repository:
