Following are the pagegenerator test failures:
For ru doomwikia:
Error in pagegenerators_tests.PageGeneratorIntersectTestCase.test_intersect_newpages_and_recentchanges
```

```

```
However, the same tests pass for en:doomwikia and it:doomwikia.
As suggested by jayvdb, this is probably caused by zero (or very little) data in special:newpages and special:recentchanges.
Upon testing the following links:
http://ru.doomrus.wikia.com/wiki/Special:RecentChanges
http://ru.doomrus.wikia.com/wiki/Special:NewPages
and
http://doom.wikia.com/wiki/Special:RecentChanges
http://doom.wikia.com/wiki/Special:NewPages
It can be confirmed that russian doomwikia doesn't contain any entries, while english doomwikia does.
It is also worth mentioning that for italian doomwikia:
http://it.doom.wikia.com/wiki/Special:RecentChanges
http://it.doom.wikia.com/wiki/Special:NewPages
RecentPages doesn't contain any data while NewPages does. Both the tests however, pass for italian doomwiki.
