Description of problem: When I add any file to the list of fax pages using hp-sendfax, the process hangs. The activity bar keeps moving, but the last thing seen in the log is: hp-sendfax[2312]: debug: 'msg=DeviceCloseResult\nresult-code=0\n' hp-sendfax[2312]: debug: text/plain hp-sendfax[2312]: debug: text/plain hp-sendfax[2312]: debug: Adding file: title='/tmp/myfile.txt' file=/tmp/myfile.txt mime_type=text/plain mime_desc=Plain Text) hp-sendfax[2312]: debug: Printer state = 3 hp-sendfax[2312]: debug: Job ID=18 (hangs indefinately) I have tried multiple files and file types with the same results. There are not permission problems with the files and they are not corrupt. The print jobs in the printer status shows "printing" for about 20 seconds or so and the "completed". I have also tried restarting the CUPS fax printer. SELinux is not enabled. Version-Release number of selected component (if applicable): hplip-1.6.12-1.fc6 How reproducible: Always
hp-sendfax also consumes 90%+ cpu when running, even when idle. It seems that this bug is probably the same as: https://launchpad.net/ubuntu/+source/python-qt3/+bug/66830 Options: 1) downgrade PyQt to 3.14 (that was inconclusive in the ubuntu thread) 2) upgrade to hplip 1.7.1

So, here is what I know so far. I tried many different combinations of PyQT and hplip from FC-5/FC-6/FC-6 updates with no luck. I did not try PyQT < 3.15 since it seems that downgrading is ultimately not the right direction. I was able to build hplip 1.7.3 and the problem goes away. I still get an error in 1.7.3 but it's totally unrelated, and I've already dug through the code and verified an upstream bug (and it only happens if you're low on toner so it's minor). I would suggest an upgrade to 1.7.3. If you have other combinations or such that you'd like me to test for you, let me know and I'll give them a try.
Verified working hplip-1.7.2-2.fc6 in updates-testing.
Great, thanks for testing.
Fixed in update: hplip-1.7.2-3.fc6
