random crashes when hidding/showing layers

[Marc Poulhiès]

Since I upgraded to preversions of inkscape, I experience random crashes when toggling the state of layers. It has been a long time (2 weeks, maybe more) that I have this problem, but I could not find something more specific. I'm updating to latest inkscape svn version, but the bug is still here. I'm currently using revision 21928, on Ubuntu Jaunty (i386). It has never crashed immediatly. I can always work for some time before it goes down. And the crashes always occur when I'm toggling the visibilty of some layer.

There is nothing helpful displayed in the console (only that it successfuly used the emergency crash routine).

I tried to find if this bug was already in the BTS, but only found problems when deleting or playing with sublayers, which I'm not doing.

I can recompile or run in debugging mode, whatever can help more :)

Looks like that in the latest svn revision (21928), the crash also happens when simply choosing a layer. That was not the case with preversion or the previous svn version I tried.

Do you have more than one window opened (from within inkscape) when the crash happens?

related bugs that I know of:

Bug #307195 in Inkscape: “crash with two inkscape instances when changing layer”

duplicates of #307195:
Bug #322143 in Inkscape: “Crash - Layers and Duplicate window”
Bug #380563 in Inkscape: “visibility toggle crasher”

possibly the same crash or related:
Bug #335183 in Inkscape: “Contuned crashes.."Inkscape has encountered an internal error..."”

!!! You're right, the "key" point is having more than one window. To get inkscape crash, i did the following:
 - open a .svg, do nothing else
 - open a new .svg, do nothing else
 - go back to the first .svg and toggle the visibilty for any layer => crash

If I play with layers on the second window, no crash. If I close the second window and then go play with layers in the first window, no crash.

I tried with more than 2 windows, and the result is strange. If I open 3 svg, and then:
 - play with layers in the 3rd window: OK
 - play with layers in the 2nd window: OK
 - play with layers in the 1st window: OK
 - play with layers in the 2nd windows: crash

I'm not sure what kind of combination I should do to help narrow the bug.
