--- Comment #7 from Michael Stahl (CIB) <michael.stahl at cib.de> ---
this bug, as reported, is a duplicate of bug 122892

there is another performance problem though, which is *not* an infinite loop
but at least in a debug build it's taking a bloody long time scaling a bitmap
inside a metafile that must be somewhere in the document to a width of 865
million pixels; this is due to these values read from the metafile:

MetaBmpExScaleAction::Read()

p maPt
$43 = Point = {
  x = 621353314,
  y = -1397620223
}
p maSz
$44 = Size = {
  width = 1917665794,
  height = 242
}

this happens while creating preview image in
SfxPickListImpl::AddDocumentToPickList() during load.

after removing this call, there's no perf issue; would be interesting to know
if the metafile causes perf problems in release build as well, which would be a
*separate* bug from this one of course...
