This seems to be a Linux only problem as I can't duplicate it in Windows 7 x64.

It's that, or one of your plugins is causing the problem. Try deactivating the ones that don't show up in the ones I'm running and see if the problem happens again.

Please explain step-by-step what you did.

[xeen]

to reproduce this go into select mode, highlight something and switch to delete mode using the keyboard shortcut (and don't move your mouse). I actually knew about this but checked the wrong variable. Patch in a second…

Thank you Xeen, it's fixed in 4348.
