Internal error when reverting

[caetano veyssières]

Operating system :
Linux MANJARO 16.10.3 64-bit (kernel 4.4.39-1-)

Inkscape
0.92 from snap package

When reverting a file, Inkscape crashes after returning this message :
"Inkscape encountered an internal error and will close now."

This doesn't happen on all files.

Steps to reproduce the bug :
- open the inkscape.svg logo in the attached zip file
- make any change (e.g. move the object)
- Click on File > Revert
- Inkscape should ask for confirmation, select OK
- The file gets reverted but the error message appears and Inkscape closes

The other attached file in the zip archive does not produce this error. However, the file format doesn't seem to correlate with the bug, as other .eps files produced the error.

<offtopic>Caetano, you're not using the prerelease version, but the trunk version. There is no ppa for the 0.92 branch.</offtopic>

Sorry, I thought the trunk version was the latest development version.
So I compiled 0.92 pre 3 and the bug is still there.

- thank you for taking the time to issue a report.
- not reproduced on Windows 10, Inkscape 0.92pre3 15195 (32 bit exe build)

Tested with r15290 from trunk ppa on Linux Mint 18:
Not reproduced.

(The ppa for LTS Ubuntu version is rather outdated. 16.10 and the older 14.04 get a build that is 2 hours old, while for 16.04 the build is > 2 weeks old... Anybody know why?)

[Mc (mc...)]

("dependency wait" : gimp and python-numpy have a problem preventing them to be installed, and since they are of inkscape dependencies, the build bots cannot build inkscape. cf the end of https://launchpadlibrarian.net/298673890/buildlog.txt.gz )

[Hachmann (marenhachmann)]

(thank you, Mc! Does this need a bug report for 'launchpad itself'?)

Not reproduced on Xubuntu 16.04, lp:inkscape/0.92.x rev. 15280 and lp:inkscape rev. 15350.

[caetano veyssières (chameleonscales)]

I installed the snap package of the new 0.92 release on Linux MANJARO 16.10.3 64-bit (kernel 4.4.39-1-) and the bug is here again for me.

[jazzynico (jazzynico)]

Fixed in lp:inkscape, rev. 15608.
Same root cause as in bug #1670688 "Internal error on closing or saving" (https://bugs.launchpad.net/inkscape/+bug/1670688).

Fix from bug #1670688 was backported to 0.92.x in
