I had some issues with workbench_rc - thg failed in tortoisehg/hgqt/init.py with ImportError: No module named workbench_rc
Installing pyqt4 development stuff "resolves" the problem at runtime by somehow creating the missing file when running from source.
I don't know what a root cause or primary solution could be, but some wild shots:
- whatever generates workbench_rc.py doesn't fail hard enough when it fails, leaving no indication what the real problem is and why it was removed in 43160a7deebd
- it is apparently not generated by setup.py - it should, especially when creating a system package where users can't generate the file in the right location at runtime
- the development packages should not be a runtime dependency - qt is huge enough as it is ;-)
