Thread:Support/Odd language mix in lqt notification e-mail from translatewiki.net

I have got a notification e-mail about my altered user_talk page on twn. It is message (in version oldid=2836668 of February, 22th)

Here is a copy of the e-mail body: Leeven Purodha, dat hee es en Nohreesch translatewiki.net, dat ene neue Diskussionsstrang zom Teema „StatusNet:Emailsummary-a06ed6130aa26671389f191e1440733bd0c8f3a4-p a href=" 1s" change your em/en“ öm 18:29 Uhr aam 24. Aprel 2011 op dä Sigg User talk:Purodha dobei jekumme es. Jeschrwevve däd_en dä Metmaacher Giftpflanze

Beloore kanns de dä op 

Der Täx es: Hallo Purodha,

du hast das auf /en übersetzt, das sollte wohl aber auf /ksh, oder?

Ene schööne Jrohß!

This e-mail has oddities: These oddities are not systematic, though.
 * 1) The result of   is from the wrong language, German (de) instead of Colognian (ksh), or 1st fallback language, not the message language itrself, that is, we read "Diskussionsstrang" (wrong) not "Jeschprääschßfäddem" (right). On the message page, MediaWiki:Lqt-enotif-newthread/ksh, it appears correct, at least when I am viewing it. My user language is ksh.
 * 2) The result of   is wrong. There is no article+preposition added, as it should be. This appears correct on the message edit page, and incorrect on the mesage page, which is a known deficiency. In the e-mail, GRAMMAR could be taken from German (de), but there are many other explanations as well.
 * 3)   at least was taken from Colognian (ksh) in the e-mail and appears to be correct.
