Re: Nokia N95-8 JPG crash



This file crashes Nokia E90 too (*#0000# says 210.34.75, 12-04-2008, RA-6, Nokia E90 (16)). In fact, E90 uses exactly the same platform as N95 (TI OMAP 2420) with same Symbian v9.2 (S60 v3 FP1), so the
crash was predictable.

	I've tested on:

- Image browser -- by pressing [Open] in File Manager, so that the
  application crashes immediately, and File Manager barking "Unable to
  open file".

- Gallery -- begins to scan all images in phone memory and card, and
  crashes soon, obviously when it encounters nokiacrash.jpg.  So, just
  putting this file anywhere in the filesystem is Gallery DoS.

- Web Browser -- does nothing when typing file:///E:/nokiacrash.jpg, but
  crashes upon <IMG SRC=nokiacrash.jpg> in HTML file (of course,
  Settings->Page->Load Content have to be set to "Images" or "All",
  otherwise IMG tags are skipped).
