Export to odg not work in 0.91 and 0.92

Please add information about OS/platform to the bug description, and attach a test case (Inkscape SVG file) to the bug report which exposes the reported issue to allow further investigation on other systems, thank you.

Windows 10 Pro French, 16 Go RAM, Core I7, SSD samsung 256 Go, Hard Drive 2 To.

I create a square, like on the screenshot and menu File / Save as ...

Error message : The 'filename.odg' file could not be saved

Not reproduced on Xubuntu 16.04, Inkscape 0.91 and 0.92. The SVG drawing is correctly exported to ODG.

Not reproduced with Inkscape 0.48.5 r10043, 0.91 r13725 and 0.92 r15299 on OS X 10.7.5: export succeeds with all tested versions, ODG file opens in LO ok.

Minor detail here: the exact position of the rectangle on the page in LibreOffice does not fully match how it is displayed in Inkscape (the objects (a rect with rounded corners centered on the page, lines connecting the rect geometric bbox corners to the page corners) scale larger in LibreOffice relative to the page size than in Inkscape). Could be due to outdated version of LO available for this OS though. Not related to recent unit changes in Inkscape (reproduces with 0.48.x too).

Reproduced with Inkscape 0.92 r15299 on Windows 10: same error message in dialog as reported, no console message(s).

on second thought, I am not sure that this backtrace is helpful. I get exactly the same backtrace if I just draw an object and close Inkscape normally without any crash.

but the failure to save is definitely real on the trunk build

gdb backtrace reported separately, as
https://bugs.launchpad.net/inkscape/+bug/1654560

I get this error with the portable versions 0.91 and 0.92 on Windows 7, 32bit. In portable version 0.48.5 the export to odg works on the same PC.

I can confirm this bug on 0.92 on KDE Neon/Ubuntu 16.04. Have the same distro installed on a workstation desktop and on a cheaper laptop and in both cases, I get the same error message as the original bug description when trying to save as an .odg file.

I've tried both "Save as" and "Save a copy" and have tried, in both, typing the extension while selecting "Guess from extension" and choosing the actual extension from the drop down list.

reproduced on Windows 10, Inkscape 0.92.2pre0 (973e216, 2017-07-25)
using the install file inkscape-0.92.2pre0-x86.exe

Reproduced on KDE Neon 16.04 with 0.91 r13725

Fix pushed to master in
  https://gitlab.com/inkscape/inkscape/commit/d61e166a900e32e6f1640c7c26b1a8a66826e51d

It seems .odg export was broken completely on Windows due to file name handling of linked raster images (even of no images were included in the file)

Should any issues persist please report back (preferably in a new bug report with detailed steps on how reproduce the issue).

Backported to 0.92.x in
