Error dialog appearing

SUMMARY


STEPS TO REPRODUCE
1. Open Krita, open an image. Choose "Filter / Start G'MIC-Qt".
2. Select filter 'Artistic / Stylize' (If not already available, update filters by pressing the 'Update filters' button). Choose one of the pre-defined style (not "Custom"), and press the "Apply" button.
3. The filter is working well until it returns. An error message appear, and the outcome is not transferred back from the G'MIC-Qt plug-in to Krita.

Comment 1 wolthera 2019-04-08 16:00:05 UTC

I cannot find the filter, can you check if it still happens with the latest Krita nightly builds?

Comment 2 David Tschumperlé 2019-04-09 07:35:06 UTC

With latest G'MIC 2.5.6 and latest Krita Appimage (nightly build)

Comment 3 David Tschumperlé 2019-04-09 07:35:40 UTC

Yes this does happen with the latest build (appimage : krita-4.2.0-pre-alpha-4022dda-x86_64.appimage, downloaded this morning).
I'm using Ubuntu 18.10 (64bits).

In the G'MIC plug-in, the 'Stylize' filter is located under 'Artistic / Stylize' (with latest filter updates, so having file `$HOME/.config/gmic/update256.gmic`).

Filter selection work, the filter is running correctly (progress of the preview window is visible). The problem comes when the plug-in sends back the image data to Krita.

Comment 4 Bug Janitor Service 2019-04-10 04:33:16 UTC

Thanks for your comment!

Automatically switching the status of this bug to REPORTED so that the KDE team
knows that the bug is ready to get confirmed.

In the future you may also do this yourself when providing needed information.

Comment 5 linuxmarc 2019-09-11 20:54:51 UTC

same crash behavior with the gmic-qt 2.7.1 version in Ubuntu 18.04.

Comment 6 amyspark 2020-10-26 13:16:27 UTC

Marking as RESOLVED UPSTREAM because this is a bug in GMic: https://github.com/dtschump/gmic/issues/260 .

tl; dr: the fx_stylize command sets the layer name to an uninitialized variable.
