• Component: New Bugs
• Status: CLOSED FIXED

[Sachin Padma]

Crash reported at http://1cad00171/mobilecrash/crashreport_text.php?id=412 occurred 5 times among 2 users on NemoW PR2.0.043.r.i.
Appears has corrupted data structures / heap problem when closing Web Browser UI.
User  panic EReqStillActiveOnDestruct = 40 is explained as follows in e32panic.h:

This panic is raised by the destructor of an active object, a CActive.
	
	It is caused by an attempt to delete the active object while it still
	has a request outstanding.

Therefore sounds like the browser UI is attempting to delete an active object before having processed an outstanding request.
