Description Peter Klotz 2012-01-21 20:52:15 UTC

Version:           1.2.2 (using KDE 4.7.4) 
OS:                Linux

After upgrading Arch Linux (x86_64) to Linux 3.2.1 when starting up Kaffeine I get a "No device found." error message although my DVB-T USB stick is attached and properly recognized by the kernel.

"kaffeine --dumpdvb" display this message:

kaffeine(3483) DvbLinuxDevice::startDevice: cannot open frontend "dvb/adapter0/frontend0"

It seems that Kaffeine tries to open the device without the leading "/dev/" attached.

If I create a symbolic link "dvb" in the current directory pointing to "/dev/dvb", Kaffeine starts without the error message and my DVB-T stick works properly.

It seems that since the upgrade to Linux 3.2.1 (or maybe another update that came in the last few days) the path used by Kaffeine is no longer correct.

Reproducible: Always

Steps to Reproduce:
* Attach DVB-T USB stick
* Kernel recognizes stick and loads firmware
* Start Kaffeine

Actual Results:  
* Kaffeine displays error message "No device found."
* DVB-T does not work

Expected Results:  
* No error message
* DVB-T should work

Another way workaround this is to first cd to /dev and then start kaffeine from the commandline.

Here's the downstream bug report:

It seems, an upgrade to udev 179 fixed the problem. I am still using the same Kaffeine version.
