confirmed on Windows XP, Inkscape rev 13646

crash message is:

**
Gtk:ERROR:gtkrbtree.c:967:_gtk_rbtree_node_find_offset: assertion failed: (node->left)

I was not able to obtain a backtrace

Also reproduced on CrunchBang Waldorf, Inkscape 0.91.x revision 13638.
Not reproducible with 0.48.5 (different gradient dialog).

[jazzynico (jazzynico)]

GDB backtrace attached (not very useful apparently).

[su_v (suv-lp)]

Reproduced on OS X 10.7.5 with Inkscape 0.91+devel r13708 and 0.91pre2 r13638.

Based on the backtraces created locally this possibly is related an upstream problem similar to [1]. Reproduced with Inkscape trunk using
- GTK+/X11 2.24.13, GTK+/Quartz 2.24.17
- GTK+/X11, GTK+/Quartz 2.24.25
- GTK+/X11 3.4.4, GTK+/Quartz 3.6.4
- GTK+/X11, GTK+/Quartz 3.14.5

Attaching backtrace from Inkscape trunk r13702 using GTK+/X11 2.24.25 installed with debug symbols.

[su_v (suv-lp)]

No longer reproduced with Inkscape 0.91+devel rev >= 14345 (the gradient list is updated as soon as the user clicks into the list, and page up/down does not trigger a crash anymore).

Rev 14345 was part of the fix for bug #1417173, and backported to the stable release branch in rev 13812.

Feel free to reopen if the same type of crash can still be triggered (maybe with different steps to reproduce).

[Alexey (allkhor)]

Reproduced on inkscape-trunk (1:0.91.0+devel+14389+60~ubuntu14.04.1).

[Alvin Penner (apenner)]

- crash reproduced on Windows XP, Inkscape rev 14391
- not sure if this is precisely the same bug, but probably related.

- open the attached file which already has a duplicate gradient defined in it.
- open the Fill & Stroke dialog, select the ellipse object
- click on the first gradient, # 4167
- hit PageDown button and get attached crash message

Gtk:ERROR:gtkrbtree.c:967:_gtk_rbtree_node_find_offset: assertion failed: (node->left)

the second gradient was produced as a duplicate of the first by using the + button. It is important to save this file before clicking on anything, in order to produce the crash. Clicking on the second gradient will normally cause it to disappear, so it needs to be saved before attempting to use the gradient.

another way to trigger it :

1) Create any shapes.
2) Change fill to linear gradient.
3) Mouse click little below gradient name(white space).
4) Press "a" (it will write an "a" , for whatever reason)
5) Mouse click little below gradient name(white space). this will put the focus there, with *no gradient selected*
6) Hit PageDown, or PageUp : Crash.

type-ahead find (in treeviews and lists AFAIK) - a Gtk+ feature.

Variation of crash with swatch list (Fill & Stroke) linked as duplicate (to be verified separately once we have a fix):

Inkscape Trunk 0.91.0+devel+15109, crash reproduced on Xubuntu 16.04 x64

[Qantas94Heavy (qantas94heavy)]

Cannot reproduce using steps in description on Inkscape 0.92.4, openSUSE TW 20190301.

[Qantas94Heavy (qantas94heavy)]

Now I can reproduce the crash, I needed an additional PgUp after the last step before it would crash.

Reproduced on 0.92.4 and 1.0alpha (75da9ac4ea, 2019-04-12).
