Description Alexander Potashev 2015-05-27 21:12:35 UTC 
See steps to reproduce below.

Reproducible: Always

Steps to Reproduce:
1. Run the "Email images" plugin, I use "./kipicmd -w -a "Email Images..." --selectedimages ~/testimages/test10*".
2. Add a few large JPEG images to the list for exporting.
3. Choose the PNG as the output format, select maximum resolution to make resizing even slower.
4. Start the exporting.
5. Click "Cancel" in the progress dialog while the images are being resized/encoded.

Actual Results:  
kipicmd crashes, GDB reports the following:
Program received signal SIGSEGV, Segmentation fault.
0x00007ffff4ff418a in QWidgetPrivate::deleteTLSysExtra() () from /usr/lib64/qt4/libQtGui.so.4

See a full backtrace below.

Expected Results:  
Resize canceled and the dialog either not closed or closed gracefully without crashing the host application.

Comment 1 Alexander Potashev 2015-05-27 22:29:22 UTC 
This happens because the Cancel button in KDialog (ancestor of class KPBatchProgressDialog) trigger QDialog::reject() which then closes the dialog. The application terminates because this progress dialog was the only window in "kipicmd".
