Crashes in GIMP 2.6.6

Hello people.

I having frequent crashes in Gimp 2.6.6, the version distributed by the
Slackware 64 12.2 version.

It seems quite random. In most cases (all except one), the crash happened
while trying to save an image - just before the file dialog appeared. The
exception crashed when the dialog was already visible. First the text
entry box didn't accept text (cursor disappeared when moved over the box).
Then, after a couple of seconds, the crash happened.

I was running gimp in gdb, hoping to do a backtrace, but detected that
Gimp had been compiled without debug info. The text appearing is:


Program received signal SIGSEGV, Segmentation fault.
[Switching to Thread 0x7ffcda5c66f0 (LWP 15429)]

        in gtkentrycompletion.c
(gdb)
(script-fu:15434): LibGimpBase-WARNING **: script-fu: gimp_wire_read():

The backtrace only showed:

#0  0x00007ffcd8f02272 in _gtk_entry_completion_popup
#(completion=0x28270f0)
    at gtkentrycompletion.c:1491

I have used Gimp quite a bit the last days, and only had problems after
using a scaling script (in Guile). Could this be the problem?

John

I recompiled a new version of Gimp (still 2.6.6) and the error remains.
But now I can get a backtrace:

It's not much, but it might help. Is this some error of mine, or should I
submit this as a bug report?

Yes please, submit a bug report:
bugs.gimp.org

Be sure to specify the GTK+ version you use, and also step-by-step
instructions on how to reproduce the problem

More likely the problem is that you are using unstable development
versions of GLib and GTK+ (as indicated in your bug report). Is there a
specific reason you are doing that? And why don't you first check if
using a stable version of the toolkit fixes your problem?

I apologize for that, and for not seeing your answer immediately (you
did Cc: me, but that msg didn't arrive). In my defense, I did check the
README file of GTK +, and did not see any indication that 2.17 was an
unstable version:

---Readme:
This is GTK+ version 2.17.2. GTK+ is a multi-platform toolkit for
creating graphical user interfaces. Offering a complete set of widgets,
GTK+ is suitable for projects ranging from small one-off projects to
complete application suites.
---

I'd say the first line of the README would be a logical place to warn
people, wouldn't it? In hindsight, I _did_ know the odd versions were
development. I guess stress got me... Just switched everything to 64 bit
here.

Will test with 2.16.4 now. Again, sorry!

John
