crashes when printing on pdf

[scarselli@…]

When I print on a virtually pdf printer I get this error

Further testing: printing to cups-pdf produces an empty ~/PDF/_stin_.pdf file

Further testing confirms the bug. It seems to be related to the complexity of the image: with only a greyscale grass raster it prints ok, if we overlay a higher resolution layer, it crashes:

use cache scale = 1.62 translate: 90, 133 draw mPlotStyle = 0 QgsComposerScalebar::render p = 0xafc7897c mComposition->scale() = 5 QgsComposerScalebar::boundingRect QgsComposerScalebar::writeSettings Resolution = 300 Paper: 420 x 297 Printing ... draw mPlotStyle = 2 mPreviewMode = 0 render Segmentation fault

Can you attach a back trace from it crashes?

[cavallini@…]

I did some more testing with r5907, and it seems to be working with simple cases, and crashing when I add several grass layers, transparencies etc.: QgsComposerVectorLegend::render p = 0xafb4707c mComposition->scale() = 5 font sizes = 71.6139 61.3833 51.1528 layer = 3 layer = 2 mSelected = 0 draw mPlotStyle = 0 QgsComposerScalebar::render p = 0xafb4707c mComposition->scale() = 5 QgsComposerLabel::render Resolution = 300 Paper: 420 x 297 Printing ... draw mPlotStyle = 2 mPreviewMode = 0 render Segmentation fault

I'm tidying up the 'crash when printing to postscript' tickets - refer to ticket #345 for further details.
