Bug report #13738
OSGeo4W QGIS dev Windows 32-bit builds crash when the Browser panel is enabled

This occurs with 32-bit builds from OSGeo4W; also happens when I compile myself, using OSGeo4W configuration.
The standalone QBrowser also crashes.
Win 64-bit builds don't appear to be affected.
running on Windows 8.1 64-bit system and Windows 7 64-bit.
For some reason (something that flashed by, I think) I had an idea that one or another of the web service providers may be related to this problem, so I removed the various web service provider .dll files and used just the file and database providers. Now QGIS/QBrowser don't crash.

406db65 is also related. I suspect there are more QString references passed to threads (via signals?) and dereferenced after the referenced QString object is already gone. Is there a big gain by passing QString references instead of QStrings? They are referencing the same internal string anyway.
