Bug report #14152

Form annotation crashs QGIS with Segmentation fault (core dumped)

Description

Trying to use Form annotation, once you select a ui file and press OK, QGIS master crashes.

This works fine in QGIS 2.8.6 following Tim Sutton instructions here:

[[https://youtu.be/0pDBuSbQ02o?t=2m25s]]

You can try to replicate the bug using the annotation_form_example.ui file with the Regions Layer of the QGIS Sample Data (Alaska Dataset). Both in attachment.

Add Region Layer to QGIS and make it active
Using the form annotation tool, click over a region polygon
Double-click the created annotation to access setting
Select the annotation_form_example.ui and press OK

If everything went well, the form should appear inside the annotation.

Instead, QGIS exits with Segmentation fault (core dumped)

But instead QGIS crashes with the followin message:

annotation_form_example.ui - Example form (1.5 KB) Alexandre Neto, 2016-01-21 05:11 AM

I cannot replicate unfortunately. Could you please try to generate backtrace? (i.e. run in gdb, when it crashes type "bt" and copy the output here).

I have used gdb and I got this:

This looks like a duplicate of #8760 - crash within Qt in QUiLoader::load

#5 Updated by Martin Dobias almost 9 years ago

Alexandre, could you please confirm whether you get a crash also if you try to use that .ui file for attribute form? In such case we could close this one as a duplicate of #8760

#6 Updated by Alexandre Neto almost 9 years ago

Status changed from Feedback to Closed

You are right, this is a duplication. I will close it and move the discussion to #8760.
