I tend to get this problem a lot more since I've switched from 24.5 to
master.

This code makes Emacs report the error immediately instead of freezing:

    (setq x-selection-timeout 10)

When the bug occurs, a fix that typically works is to:

1. kill some text while in Emacs.
2. copy the text from outside
3. wait for 3-4 seconds before attempting to paste into Emacs

Step 3 could be important, since if I paste quickly, the bug seems to
re-occur more often.
