Crash when opening the file dialog via 'Export PNG Image > Export as' (Windows, trunk)

[Alvin Penner]

Windows 10, Inkscape 0.92+devel 15506

- open Inkscape and load the attached file rotate_0.svg
- open XML editor and set the namedview property inkscape:document-rotation="90"
- note that the entire canvas rotates by 90 degrees as expected
- go to File->Export PNG Image
- click on Export As in order to specify a location
- get a popup message saying "Unspecified fatal error encountered, aborting"
- get a Microsoft Visual C++ runtime error
- get the DOS messages

Crash not reproduced with lp:inkscape r15507 on Ubuntu 14.04.5 LTS.

reproduced on Windows, trunk rev 15444

Alvin, could you provide backtrace?

[Jabiertxof (jabiertxof)]

thanks

[Alvin Penner (apenner)]

yes, here it is

[su_v (suv-lp)]

I wonder whether the crash reported here has same underlying issue as with bug #1663884 (missing GSettings schemas).

Just curious - this does not reproduce with an unrotated document? What if you use native dialogs?

[Alvin Penner (apenner)]

wow, this is embarassing, I get exactly the same result if I load rotate_0.svg and try to export it. backtrace is the same as well. Never tried that test before.

[Alvin Penner (apenner)]

for what its worth, I just re-tested using the file rotate_0.svg and using rev 15443, and got the same crash. So it is not related at all to rev 15444. I was focussing especially on rev 15444 because of the crashes that I was seeing in Bug 1663697
https://bugs.launchpad.net/inkscape/+bug/1663697
and Bug 1662531
https://bugs.launchpad.net/inkscape/+bug/1662531

I think this must be what is called tunnel vision, where you see only what you want to see.
Anyways, I apologize for the confusion, and I will go back to these other two bugs and re-test them to see if I can get some backtraces.

[su_v (suv-lp)]

Would you mind testing the issue reported here (crash with 'File > Export PNG Image > Export as') with native file dialogs? In Inkscape 0.92 (GTK2), the 'Export as' dialog uses the native Windows or the GTK file chooser, depending on the user's preference setting; probably this is the same with trunk GTK3 builds:

Edit > Preferences > Interface > Windows > Desktop Integration:
[x] Native open/save dialogs
[ ] GTK open/save dialogs

[su_v (suv-lp)]

On Windows 10:
- not reproduced with Inkscape 0.92.1pre1 (GTK2) from inkscape.org
- reproduced with inkscape_trunk_r15113 (GTK3) from
  http://download.tuxfamily.org/inkscape/win64/

I apologize for the misleading question in the prior comment: the issue seems unrelated to the type of open/save file dialog (native, GTK). On a closer look, the 'Export as' button on Windows always opens a native file chooser dialog (see also bug #1071104 comment 1).

[su_v (suv-lp)]

Crash no longer reproduced with inkscape_trunk_r15113 after downloading the schemas from the devlibs64 repository:
 http://bazaar.launchpad.net/~inkscape.dev/inkscape-devlibs64/trunk/files/head:/share/glib-2.0/schemas/

and copying them into
 share\glib-2.0\schemas\
inside the unpacked trunk build.

The same workaround also stops the crashes as reported in bug #1663884.

AFAICT this is a packaging issue with GTK3-based applications compiled on/for Windows.

Fix committed in r15514

Thanks su_v for figuring this out!

@Eduard: Is this fixed in the official Windows packages for 0.92.1?

(at least here is a question that sounds like it's the same issue:

[Patrick Storz (ede123)]

This issue was only relevant to gtk3 builds, so 0.92.1 is not affected.

[Hachmann (marenhachmann)]

Mmh, okay... sorry. Thank you for jumping in on the discussion in the answers section!
