Hello folks,

confirming.

All official downloads are dead but some file hosters still carry it:

http://downloads.ziddu.com/downloadfile/6637188/P2kCommander-V6.0.0.zip.html

The app prepares a .gif image in memory which is passed as OLE stream to
OleLoadPicture().
Wine's 'ungif' lib, part of 'windowscodecs' doesn't like it and flags the .gif
image as broken, hence the failure.
The app doesn't expect a failure here and proceeds to call a method on the null
picture object.

Microsoft's OLE image decoder can cope with this and happily returns a picture
object.

I dumped the .gif from memory and it gets indeed reported as "broken" (giflib
code is probably shared/similar).

--- snip ---
$ identify dumped.gif 
dumped.gif GIF 160x149 160x149+0+0 8-bit PseudoClass 16c 2.42KB 0.000u 0:00.000
identify: corrupt image `pic.gif' @ error/gif.c/PingGIFImage/961.
--- snip ---

Wine Internet Exploder can still display it though.

Interesting tidbit why only the combination of two 'winetricks' recipes work:

'vcrun6sp6' installs 'asycfilt.dll' which is the MS OLE image decoder, needed
by native OLE.
The decoder lib is loaded on demand - when OLE picture API is used.
Failure to load the library (if not present) just results in common 0x80040005
OLE error code.
