Server Error 500 after delete album in Gallery 1.5.2

I choose an album with tv "galleryalbumlist" for a webpage and afterwards another author deleted right this album from the Gallery-Component. Now the page throws an 500-Error, even if I try to catch the errror with Output-Filters ("notempty"). Moreover, the error occurs even I take away the Gallery-Call all in. That means, if I use the tv "galleryalbumlist" and I fill it with a wrong value, everything getting bad with my webpage, there is no safety net.

Can anyone show me an idea to solve this? for instance, if the formerly choosen album didn't exist anymore, nothing is shown on webpage, where the album should be.

I Use Gallery 1.5.2 - MODX 2.2.4

Sincerely,
Rainer
