Linux app crashing when opening "Guest Apps" tab

[chqoot-vgxu]

The windows server seems to return a list of app with at least one None value inside.
Tested on versions alpha, 0.2 and 0.3 with windows in a qemu vm.

Thank you for reporting, i will make a commit soon that will fix this problem !

[chqoot-vgxu]

I did some testing, apparently for one app (wt), it returns None for both description and version, hence the crash. I don't know if it's my VM broken nor if it's fixable in some way.

EDIT: I disinstalled wt and that fixed it, probably a problem on my side, closing

I see you closed the issue, but after the latest release this error should be handled properly and should not result in a crash ! :)

[chqoot-vgxu]

Good to know! I closed it because I thought it was a problem with my machine, maybe one of the cleanup scripts that I tried deleted the wrong file/registry key
