 This is a bug - I can reproduce the exact same behavior.

 The problem is when the custom event is processed for a lirc key press
 (mythmainwindow.cpp line 1517) the text variable only ever gets set if
 the keycode has a Qt::UNICODE_ACCEL modifier which never seems to be the
 case.  The result of this is the QKeyEvent that gets sent doesn't have
 the  text parameter set to anything so when the guide grid tries to
 convert it to an integer it always fails. QKeyEvents from the keyboard
 always have  the text set so that works  OK.

 A quick fix is to comment out line 1534 in mythmainwindow.cpp so that
 text always get set but don't know enough about this code to know what
 the consequences of this are. Anybody familiar with this code care to

 I wonder if this has ever worked or has something changed? Could be
 related to the switch to Qt4.
