import crashes when Image DPI is From file

[scribblemaniac]

I recently came across a PNG file that Inkscape was not able to import. When importing the image, if the Image DPI import setting is set to From file, then Inkscape shows an alert saying that it has encountered an internal error and shuts down. It does not crash however if the DPI import setting is set to Default import resolution. I have attached a plain image that consistently exhibits this behavior.

Inkscape version: 0.91
Operating system: Mac OS X 10.10

Crash reproduced with 0.91 r13725 and 0.91+devel r14267 on OS X 10.7.5 - AFAICT thus not a duplicate of bug #1398521 or bug #1410793.

Full backtrace of Inkscape 0.91+devel r14260 attached.

Apparently not. The images affected by the Cairo size limit don't render, but don't crash. Here, the application crashes in (or just after) 2geom. Maybe an issue with the very low resolution of the file?

[Mc (mc...)]

fixed in r14307

[Mc (mc...)]

(the problem was that the scaling factor was "floored" to 0.1 precision, and not "rounded", so that with big scales it was floored to 0.... and numerical hell followed. (dividing by 0 led to "inf" values -which did not provoke the crash, but led to "nan" values, which did-)

Thank you! Good job tracking down and fixing the bug :D

Fix backported to 0.91.x in rev 13833.
