Description Benjamin Berg 2006-02-18 02:27:58 UTC

When opening the attached pdf in evince, poppler unions a GdkRegion with rects
with negative width and/or height. This causes an assertion faliure (later on)
with newer gtk versions.

A little more info is at http://bugzilla.gnome.org/show_bug.cgi?id=331467

Created attachment 4648 [details]
pdf file that causes the crash

Comment 2 Pascal Terjan 2006-09-10 05:44:46 UTC

Is this bug still there (no crash here) ?

Comment 3 Benjamin Berg 2006-09-10 11:28:12 UTC

This will not crash anymore. Newer GTK+ versions just ignore these rectangles
with negative height/width.

One needs to check if poppler_page_get_selection_region still adds rectangles
with negative width/height to the GdkRegion.

Doesn't crash for me, closing, please reopen if you can still reproduce a crash

Comment 6 Benjamin Berg 2009-06-20 11:14:45 UTC

Yes, the PDF file will not crash anymore, as GTK+ now has more sanity checks (see the original GTK+ bug report). However, it may be a good idea to still investigate how the negative sized areas happen.

I just noticed that the selection is also redrawn wrong. If one selects a bit of the map (just click and drag a short distance) and then forces a redraw a set of selection rectangles appear. These are also visible if one presses ctrl+a.

Comment 7 Benjamin Berg 2009-06-20 11:17:03 UTC

Oh, and the text that belongs to those selection rectangles can actually be seen on the lines that run from top to bottom in the center (and also some text).

Comment 8 Albert Astals Cid 2011-06-19 14:47:50 UTC

Don't see a bug here anymore. Please reopen if it still crashes for you.
