Emulator

What's the problem?
Using OpenGL plugin, every time I try to exit from the emulator (hitting the ESC key), Dolphin crashes showing 3 "memory could not be read" errors in a row.

Dolphin version with the problem (as it appears in the title bar, Ex.: "R
4779" or "R 6403M"):
r7190 and later (but couldn't find r7188 and r7189 to test)

(optional) Dolphin version that does not have the problem:
r7187

Operating system and version:
32-bit or 64-bit:
Windows XP SP3 32bit, e8400, hd4850

Game ID (as it appears in game properties, Ex.: "GZ2P01" or "RSBE01"):
Every game

Build command-line (not on Windows):

Was the ISO a plain dump from disc, compressed and/or scrubbed?
Plain dump, happens on both compressed and not compressed games

Please provide any additional information below.
I suspect that it was r7189 the cause of the problem, but I cannot be sure because as I said I couldn't find that build.
