Subject: Check for namespace existence in Title::makeTitleSafe().
X-Git-Tag: 1.31.0-rc.0~23929^2
X-Git-Url: http://git.cyclocoop.org//%27%40script%40/%27?a=commitdiff_plain;h=9eb25dc032c7408c96af78253ac512fd3ceb2231;p=lhc%2Fweb%2Fwiklou.git

Check for namespace existence in Title::makeTitleSafe().

Namespace existence has to be checked before calling Title::makeName() because otherwise it will fallback to a page with the same name, but in the main namespace which is not what we want here.
