crash when creating new grid after duplicate window close

[Johan Engelen]

From bug 179982

1. Start Inkscape
2. Duplicate window
3. close Duplicate window
4. enable grid (#) in original window
> Inkscape crashes with the same error as in screenshot newgrid.png

If you first enable grid in step 1, and disable in step 4. you get crash but without the error message.

[Johan Engelen (johanengelen)]

Fixed. When SPDesktop is destroyed, it was not removed from SPNamedview. very bad indeed! this is fixed now.
However, another bug still lives with similar trigger:
1. Start Inkscape
2. Duplicate window
3. draw a rectangle in the duplicate window
4. close Duplicate window
5. enable grid (#) in original window
> Inkscape crashes, with emergency crash

[Johan Engelen (johanengelen)]

Can no longer reproduce :S
Can anybody comment please whether this really got fixed by my fix?

[Johan Engelen (johanengelen)]

Assigning off me, so others might have a look at it.
I just reproduced it. So please ignore my comment of 2008-01-20.

[Bryce Harrington (bryce)]

I'm not able to reproduce it, using these steps, however perhaps we should leave it open since you suspect it's still there. However I'm going to drop the milestone since it doesn't seem to be too visible.

[Johan Engelen (johanengelen)]

These are the steps:
1. Start Inkscape
2. Duplicate window
3. draw a rectangle in the duplicate window
4. close Duplicate window
5. enable grid (#) in original window
> Inkscape crashes, with emergency crash

[Christophe Dehais (christophe-dehais)]

I was not able to reproduce with the above steps.

[prkos (prkos)]

I can confirm all 3 scenarios on WinXP, 0.46+pre4

The error message is always the same, "internal error" and autosave info.

[Rygle (rygle)]

Has anyone been able to reproduce this on Linux, or is it windows only. Please be specific about builds that do or don't crash.

Johan?
Bryce - ubuntu
Prkos - Win32
Christophe?

Thanks

[Rygle (rygle)]

I have just posted the debug stuff for pre4 on SF now. Please try and do a backtrace if possible;
* Put the files in the inkscape directory
* From a command prompt in that directory, type;
..>gdb (enter)
(gdb) file inkscape.exe inkscape.dbg (enter)
(gdb) run

May give an error about and xml file sigsev - type
(gdb) continue (enter)

Now it should run, and if you can reproduce the crash, then go to the command window and type bt (enter)
Copy the info into the bug report.

Thanks, Rygle

[prkos (prkos)]

These are my results from fedora 7, Inkscape dev build Jan 10th

1. scenario
crash, internal error message

2. scenario
no crash

3. scenario
crash, internal error + autosave info message

[prkos (prkos)]

On winXP pre4-2 all 3 scenarios freeze in gdb, bt looks the same but Im including them all here :

[Johan Engelen (johanengelen)]

This is still present in svn 20059.

Seems the listener to sodipodi:namedview XML is not removed when closing the duplicate window?

[Diederik van Lierop (mail-diedenrezi)]

Can't reproduce this on Fedora 10 using revision 21506

[su_v (suv-lp)]

Inkscape 0.46+devel r21461on Mac OS X 10.5.7

no crash either way.
noticed console warnings: toggling grid on/off in original window after closing duplicated window produces 3 warnings for each toggle. No warnings occur when toggling grid view without/before duplicating the window.

[Alvin Penner (apenner)]

cannot produce a crash in Windows nightly build 21460

[su_v (suv-lp)]

Inkscape 0.46+devel r22293 on OS X 10.5.8

cannot reproduced this crash with any of the 3 above listed scenarios. Can we close this bug as 'Fix released'?

Note: still see these Glib-GObject-WARNINGs though:

[jazzynico (jazzynico)]

Not reproduced on Windows XP, Inkscape 0.46, 0.47, 0.48.2 and trunk revision 10760, and on Ubuntu trunk revision 10760.
Did someone manage to reproduce it recently?

[jazzynico (jazzynico)]

Closing "Fix released" in 0.47. Don't hesitate to reopen if the bug reoccurs.
