[Grub-dev] grubng c# 0.7.5 (winxp) suddenly stops working

[ab]

having run grubng c# 0.7.5 on winxp for a while now it stopped working
after uploading a finished crawl set (arc file) successfully.

it tries to download the next workingset or did, i am not sure and then
it crashes with a hard mono error.

tail of error.log shows the follwing:
