Do you enter the su-command after konsole has started, or do you pass the su-
command via the -e comman dline option of konsole? 
 
What do you mean with "trying to read files with no read-permission" ?

I'm encountering a crash with the exact identical stack trace, also running under Slackware 9.1's KDE 3.1.4 package.

When I tried to perform

more /etc/gconf/schemas/gkb.schemas Konsole crashes right away before any output.

Then I tried to more another file, clock.schemas.  It displays the first page of the contents of the file (it is bigger than 1 screen so I have to press space for more), and then Konsole crashed immediately after the keypress, with the same stacktrace.  The same thing happens with the command cat and less.

What's interesting, when I tred some other file it did not crash. (remote.schemas), and, if I only 'head' clock.schemas, it also does not crash.

These results are reproduceable consistently.  I suspect that it has something to do with 8-bit characters.  I start KDE with LC_ALL=zh_TW.UTF-8 startx, if it helps.
Comment 9 wy2lam 2004-03-07 03:45:42 UTC 
Regardless of previous messages about permissions - I don't think it has something to do with permissions, because the files I'm trying to read, I have read permissions on them.

All the above operations when performed under xterm, produces the expected results.

I have tried some other files, themus.schemas.  When I 'tail' the file, it displays correctly, even the Chinese characters.  In fact, 'tail' on all the above files generate the expected result.

So it can be something related to displaying a UTF-8 character where a font is not found, or something like that.

One last observation: when I set LC_ALL to C, Konsole does not crash AT ALL when displaying these files.

Hope it helps.

Doesn't happen on 3.2.1 anymore.  Good work...
