Description alberth289346 2013-12-17 10:05:32 UTC 
Description of problem:

After selecting and removing a package, click at "package dependencies". A window pops up with a Python stack-trace (and also the text is dumped onto the console):

Exception: Traceback (most recent call last):
  File "/usr/lib/python2.7/site-packages/yumexbackend/yum_server.py", line 1504, in dispatcher
    self.parse_command(args[0], args[1:])
  File "/usr/lib/python2.7/site-packages/yumexbackend/yum_server.py", line 1486, in parse_command
    self.get_dependencies(args)
  File "/usr/lib/python2.7/site-packages/yumexbackend/yum_server.py", line 779, in get_dependencies
    deps = self.yumbase.findDeps([po])
  File "/usr/lib/python2.7/site-packages/yum/__init__.py", line 3062, in findDeps
    reqs = pkg.requires
AttributeError: 'NoneType' object has no attribute 'requires'


Steps to Reproduce:
1. start yumex (I run it from a terminal)
2. it comes up empty (no updates to install)
3. type a package name (in my case "berusky"), and select the packages you want to remove.
4. click "apply"
5. wait until the packages are removed, the window is again empty.
6. click "package dependencies" (bottom icon at the right/bottom-half of the window).
7. the stack-dump is produced.

I reproduced this on two occasions, so the actual package being removed is probably not relevant. Maybe not having updates to perform is not relevant either.

The console session (after replacing my home-directory with $HOME)
