5066	myth_system broken by MYTH_SYSTEM_DONT_BLOCK_PARENT	pebender@…	Isaac Richards	"With the addition of MYTH_SYSTEM_DONT_BLOCK_PARENT in changesets 16153 and 16155, myth_system does not all input events when MYTH_SYSTEM_DONT_BLOCK_PARENT is used.

You can see this by using LIRC to exit mythbrowser lauched by either MythBrowser or MythNews. Not only does mythbroswer process the Esc, but mythmainwindow does as well. This causes MythBrowser or MythNews to incorrectly exit when mythbroswer exits.

I believe that the problem is caused by when the qApp->processEvents() call is made in myth_system. Since it is not called after the child process exists, I believe there is a chance of a race condition that results in myth_system exiting and re-enabling input processing before the LIRC Esc has been discarded.

If qApp->processEvents() is called one last time after the child process exits, then the LIRC Esc event is flushed. This can be done by moving the location of the call.

The attached patch makes the change and fixes the problem for me."	defect	closed	minor	unknown	mythtv	0.21-fixes	low	fixed			0
