#### Notes
I get the following error message when I attempt to view a log entry:
```
Internal error
[W0ScCgpAIC0AADwyetQAAAAA] 2018-07-10 11:44:10: Fatal exception of type "MWException"
```
Here is the most specific URL I can get to generate this error:
https://en.wikipedia.org/w/index.php?title=Special:Log&offset=20070819174422&limit=1&type=move&user=Physchim62&page=&tagfilter=&subtype=
Any attempt to view this offending log entry as part of a set of 50, for example, also coughs up an error (which is how I found this bug):
https://en.wikipedia.org/w/index.php?title=Special:Log&offset=20070822145846&type=move&user=Physchim62&page=&tagfilter=&subtype=
The offending log entry can be accessed through special:contributions as follows:
https://en.wikipedia.org/w/index.php?title=Talk:Social_situation_in_the_French_suburbs/Archive_1&diff=prev&oldid=152281672
Also notice that clicking on the link "Talk:Allegations of French apartheid/Archive 01" throws an internal error as well, presumably because it's trying to access the logs.
If the doubled namespace in the target title is the problem, there are probably a lot of similar situations out there.
