Save as Image: crash if existing filename is selected

[qgib]

Author Name: Sandro Santilli (@strk)
Original Redmine Issue: 7290
Affected QGIS version: master
Redmine category:gui

---

When I try to save the map as an image and select an existing filename, qgis crashes.
This happen both by clicking on the existing filename or by typing its name.
When typing, the crash happens as soon as I type the last letter of the existing filename.
When clicking on an existing file, the crash happens on click.
This is with current master (d628c2c).

Last logs shown on terminal are:

YES ! (just tested it) -- should "Affected version" point to oldest affected version ?

I got this same backtrace and crash as of 83445af by simply selecting an existing directory to enter it, so may not be related to "save as image" but generally to file browsing.

How do I build including debugging symbols again ? My current cmake call has -D CMAKE_BUILD_TYPE=Debug

how did you obtain that version informatoin ? it's missing a commitish. Can it be a build configuration ?
My config:
-D GRASS_PREFIX=/usr/local/grass \
-D CMAKE_BUILD_TYPE=Debug \
-D WITH_INTERNAL_SPATIALITE=1 \
-D WITH_STAGED_PLUGINS=ON \

Maybe CMAKe-BUILD_TYPE has an effect here ?

Also maybe these have a role too:

-- Found PythonInterp: /usr/bin/python (found version "2.7.3")
-- Found Python executable: /usr/bin/python
-- Found Python version: 2.7.3
-- Found Python library: /usr/lib/libpython2.7.so
-- Found SIP version: 4.13.2

I tried with a clean rebuild, same problem. Can be reproduce as easily as starting up qgis (from build dir), File->SaveAsImage, select any item shown in the select file window

in the "help" dialog

My config:
-D GRASS_PREFIX=/usr/local/grass \
-D CMAKE_BUILD_TYPE=Debug \
-D WITH_INTERNAL_SPATIALITE=1 \
-D WITH_STAGED_PLUGINS=ON \

I usually use the revision available through the nightly-build repository for Ubuntu, the one to use together with the Ubuntugis one, so everything is installed from packages, nothing compiled by hand.

Bingo! I was affected by this:

Uninstalling the qt-at-spi package fixed it!!
