backtrace from pressing okay in page style dialog

Was able to get it to crash from pressing OK in the page style dialog and will
attempt to do it from a debug daily build.

It could be related to RenderContext. It appears that (for some reason) - we're
re-painting at a time when the window this VirtualDevice is being associated
with has no screen (which is rather odd in itself) - perhaps it is not yet
realized itself.

The critical bit is:

I guess the mrOutDev passed to the buffer-device:

impBufferDevice::impBufferDevice(
OutputDevice& rOutDev,
const basegfx::B2DRange& rRange,
bool bAddOffsetToMapping)

is busted in some way.

Tomaz - can you have a look ? this may intersect with some problems we're
seeing with GL rendering in the drawing-layer too.

Thanks for the help getting a trace; and it's unfortunate that it's not
reproducible - I guess deep code-reading needed.

Interesting; I like the zooming in & out stuff ... is it possible that you have
OpenGL enabled ? can you check your help->about - if the hash of the version
has -GL at the end that is so.

I can't reproduce here sadly; thanks !

No OpenGL isnt enabled. It was hard to reproduce as it would happen randomly
and i couldnt find an exact set of steps to reproduce it everytime, but it did
happen on two different computers.

This one is similar to the stacks from Bug 91880 and Bug 92213.

So i guess the saga continues. Bug 92213 is RenderContext issue, so should this
be set to block bug 91488?
