Bug 51879 – [Symbian] Adobe flash Lite plugin on Symbian needs null window quirk

• Component: Plug-ins
• Status: RESOLVED FIXED

[Leonid Ebril]

WebKit crash on Symbian if Adobe Flash Lite plugin (version 10) unloaded.
The PluginQuirkDontSetNullWindowHandleOnDestroy needs to be set for the Adobe Flash Lite plugin on Symbian so the window does not get unset when destroying the plugin. Setting the PluginQuirkDontSetNullWindowHandleOnDestroy  flag fixes the crash.

Title for the bug is missing. Use "[Qt][Symbian]" as a prefix in the title as this issue is specific to the Symbian port of QtWebKit.

Fix English - Setting a NULL window handler on destroy crashes Symbian port of QtWebKit, use PluginQuirkDontSetNullWindowHandleOnDestroy quirk for Adobe Flash Lite 4 (Flash 10 or newer).

> Source/WebCore/plugins/symbian/PluginPackageSymbian.cpp:58
> +	    determineQuirks (mime[0]);

Perhaps make the call before "m_mimeToExtensions.add" line. I do not see a particular reason to call determineQuirks() between the two m_mimeToDescriptions.add.. lines.

We should say null, not NULL. It is null/somethingNull in Qt API's and in C++0x it is called nullptr.

flashVersionTen seems more proper.

comments need a dot at the end. ie. be proper sentences.
