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.

Thanks, added to description.

Sounds like it's related to T199216

The log entry can be viewed using the API (https://en.wikipedia.org/w/api.php?action=query&list=logevents&lestart=20070819174310&letitle=Talk:Allegations%20of%20French%20apartheid/Archive%2001) - the talk page moved to a title that is now invalid and the prefix of "Special:Badtitle/" in the log entry is similar to T190477. The move from the invalid title doesn't have that prefix and can be viewed in Special:Log (https://en.wikipedia.org/w/api.php?action=query&list=logevents&lestart=20070819174422&leuser=Physchim62&lelimit=1 and https://en.wikipedia.org/w/index.php?title=Special:Log/Physchim62&offset=20070819174436&limit=1&type=&user=Physchim62) but it could also be the difference between an invalid title in "title" and one in "params".
