Zim 0.48
Ubuntu + KDE desktop
Linux motey-desktop 2.6.32-25-generic #45-Ubuntu SMP Sat Oct 16 19:48:22 UTC
2010 i686 GNU/Linux
I was cut and pasting to insert a graph and it had a very long line. The entire
desktop crashed and killed all other programs.
As a programmer it looks like a buffer over run issue. The same data formatted
with a smaller line length did not cause the crash.( I am quite aware that a
string over run can be used to compromise a machine and so I have labeled it
security issue.)
It is possible that the writing outside of the data boundary happened in
another library and I am afraid to replicate it unless requested to do so.
I was at pasting into insert diagram window when it happened.
The data below is the single line inserted:
digraph structs { node [shape=plaintext] struct1 [label=< <TABLE
BORDER="0" CELLBORDER="1" CELLSPACING="0"> <TR><TD>left</TD><TD
PORT="f1">mid dle</TD><TD PORT="f2">right</TD></TR> </TABLE>>]; struct2
[label=< <TABLE BORDER="0" CELLBORDER="1" CELLSPACING="0"> <TR><TD
PORT="f0">one</TD><TD>two</TD></TR> </TABLE>>]; struct3 [label=< <TABLE
BORDER="0" CELLBORDER="1" CELLSPACING="0" CELLPADDING="4"> <TR> <TD
ROWSPAN="3">hello<BR/>world</TD> <TD COLSPAN="3">b</TD> <TD
ROWSPAN="3">g</TD> <TD ROWSPAN="3">h</TD> </TR> <TR> <TD>c</TD><TD
PORT="here">d</TD><TD>e</TD> </TR> <TR> <TD COLSPAN="3">f</TD> </TR>
</TABLE>>]; struct1:f1 -> struct2:f0; struct1:f2 -> struct3:her
wc says it is 671 characters.
If I can help with Zim as a programmer let me know. I really like the program
and have used it for years. It is very useful.
I can do the debug on this issue if requested. I am familiar with assembly,
Python, perl, C, C++, and hardware. I assume it is a string copy to a string
buffer of 512 or so. I have gotten into the source for perl Zim on many
occasions and also the Python version to change little things back when certain
things were incomplete. This is a clean install from debian and I have made no
mods to the code or I would not report the bug.

If you want me to debug this, just let me know, I would be glad to do
it.
And thank you again for such a wonderful and useful program.
