Update: Alexandre seems to think that this can be fixed in wine, until the hacks
are removed from the X11 sources, and the X patch can be invalidated.  See below.

In general yes, but in this case it's Wine that is creating the huge
bitmap, and that could easily be avoided.

>From what I understand, WinRAR creates several small bitmaps, and then wine
renders it all as 1 big bitmap, which X cannot handle due to the cause of this
report, and so therefore X returns a BadAlloc call, to prevent some sort of
over-/under-flow...  Wine, according to Alexandre and some others on the list
can work around this by properly rendering the images as several small bitmaps,
instead of 1 large one..  How long it will take to get that done, I dunno, which
is why the next post to this bug by myself will be linking this bug to a metabug
tracker for the ¨Xorg Pixmap patch issue¨.
