#11168: mythbrowser and mythnews crash when interrupted
------------------------+--------------------------------------
Reporter: jkt@… | Type: Bug Report - Crash
Status: new | Priority: minor
Milestone: unknown | Component: Plugin - MythBrowser
Version: 0.25-fixes | Severity: medium
Keywords: | Ticket locked: 0
------------------------+--------------------------------------
when a page load is interrupted before completion mythfrontend crashes in
QObject::disconnect() at sender->metaObject(). after much debugging i
found removing a portion of [1399a9c136] sidesteps the problem; it seems
mixing delete QWebPage, delete QNetworkAccessManager and pending replies
is an explosive combination.
the attached patch lets mythbrowser and mythnews survive interruption, but
doing so most likely reinstates #9802.
crashes using branches fixes/0.25, fixes/0.26 and master against libqt4
versions 4.7.4 and 4.8.3, though i did not test all permutations.
