xmgrace with LessTif crashes when Esc key is pressed on menu

[Wirawan Purwanto]

Binary package hint: lesstif2

I am using Ubuntu 7.04 . The LessTif package that I used was: lesstif2 version 0.94.4-2 . The xmgrace version was 5.1.20-1, although I could reproduce the same bug exactly with 5.1.21-1 also.

How to reproduce:

Try bringing up the xmgrace program, then play around with menu with keyboard. Say, press Alt+F , then Right or Left . The menu will be stuck (would not navigate anymore with keyboard). That's bug #1.

So, you are desperate, right? Try pressing Esc now. If it did not do anything, try it again. BOOOM! The program will crash and xmgrace will print the following in the stdout/stderr:

An easier way to reproduce the bug is this:
1. bring up xmgrace
2. press Alt+E
3. press Esc , and BOOM!!

I would note that I recompiled the same grace package with OpenMotif 2.3.0, and these problem disappear altogether. So, whose fault is this? I would say, but not definitely, LessTif.

This might give you a hint of what's the problem is:

The items listed on the menu bar are: File, Edit, Data, Plot, View, Window, and Help. The crash abovementioned happens when you press any of the Alt+key to access the menu items and Esc afterward, with the exception of Alt+F (File menu). I tried many times, and the program did not crash at all. So it may be something related to the internal representation of the menu list, or what.

I can confirm this bug

I'm using Ubuntu 8.10, and i could reproduce this error in three different machines. With 32 and 64 bits kernels distributions.

I could reproduce the bug just like Wirawan Purwanto described.

I can reproduce this in Intrepid too.

When I go to Help/Comments, i check the FAQ and found this:

Grace crashes with "Oops Got SIGSEV" (on GNU/Linux)
http://plasma-gate.weizmann.ac.il/Grace/doc/FAQ.html#ss5.3

I don't have time to investigate more, but that FAQ seems to have pointers.

This is the output of the command "grace -v" on my machines is:

Possible patch (from upstreams tracker)

Beware, it just reverses an upstream patch from 4.5 years ago. May need some tweaking to still apply the old patch

[Paul Gevers (paul-climbing)]

The bug has been fixed in Debian. You can watch bug 369383 for the progress on sync to Ubuntu.

[Paul Gevers (paul-climbing)]

lesstif2 version 1:0.95.0-2.3 has entered karmic (Ubuntu 9.10) and fixed this bug.

Please reopen this bug if you think is it not fixed properly.

Launchpad couldn't import bug #356017 from Debian Bug tracker.

I filled a bug against Launchpad [1] but I want to close the debian bug.
