Short description of error
One to five minutes after opening a .blend file the keyboard input stops being registered. This includes shortcuts, the text editor and any other widget that allows keyboard input. The UI is not frozen, I can still click everything and control blender with my mouse. This only happens inside of blender no matter what state the UI is in. I can still e.g. use Alt+Tab to switch windows. When closing and reopening a file the problem is gone but reappears after a few moments.
Neither the internal 'Info' console nor the linux terminal show anything that could be related to the issue.

Exact steps for others to reproduce the error
There doesn't seem to be a specific trigger for this error. It happens in the order of 1 to 5 minutes after opening a .blend file regardless if it was just created or if an existing file is being loaded.
