Maya crashes when unloading plugins

When i`m trying to unload a plugin from within Plugin manager window Maya crashes without any error messages.
How to fix this? Or i cant do this in linux version.

Distro is ASP Linux 9.0 (RH compatible).

And one more problem that i have is - when im toggling panels with spacebar, it seems that when im moving mouse maya won`t toggle panels. i should stop mouse and only then press spacebar - then it works.

Its very annoying and i dont know what to do.
Can somebody help, please?

I believe this has been in the release notes for maya for many versions. Unloading plugins may crash maya. Fact of life, can't do anything about it.
