works for me. can you provide a debugging backtrace?

How do I do get a backtrace?
I had two .tif image layers, if that helps.

To get backtrace you need to unset core file limit in shell:
ulimit -c 100000
run qgis and get crash and then run
gdb -c <your_core_file> /path/to/qgis/executable
and type 'bt' in the debuger.

Yes it would be useful if you could place the files on web.

I did some more testing, and it can happen with only 1 layer. The layer is a Digital Raster Graphic from [http://www.granit.sr.unh.edu/]. It is .tif, ~20Mb. OTF projection is off, and it happens with two different projections of the layer.
It doesn't happen if the layer is disabled (not visible).
Other raster layers (.jpg) do not have this problem.
I'll try to get a backtrace soon.

Here's a backtrace for this bug:

Thanks for the backtrace. Please could you also specify exactly which raster layer is crashing QGIS and with what projections?

printcrash.qgs is just a QGIS project file, can you also post
the layer data (drg181.tif and drg181.tfw) or put them somehre
on the Web?

Radim

It is probably this file?:
http://www.granit.sr.unh.edu/cgi-bin/load_file?PATH=/data/database/d-webdata/drg/drg181/drg181.html

Yes, that's the file. The GRANIT site doesn't seem to have a direct link to the file itself, so you probably have go here: [http://www.granit.sr.unh.edu/cgi-bin/load_file?PATH=/data/database/index.html], search for quad 181, and then download the DRG (If you haven't already). Unfortunately, it's too big to for me to put online easily.

Works for me with drg181.tif + drg181.tfw on Linux with QGIS revision 6189
and Qt 4.2.2. Please test again on Windows with the next QGIS build.
