Bug 769

I forgot to add that Ark works fine in my two other TDE environments.

This still looks like it happens deep within the system libraries.

Are you sure this is a SIGSEGV?  Could it be a SIGABRT or bad file descriptor instead?

You'll have to help me to answer your question. I don't understand those terms. :)

All I know is when Ark crashes I get the crash dialog box on screen. I selected the Backtrace tab and pasted the results here.

Let me know what details you need!

More info: I use the same TDE hard drive partition in a 350 MHz PII with 448 MB of RAM. (Removable hard drive bays. :) ) No crashing with that box. Could (a lack of) memory be the problem? I have a 1GB swap partition.

Also of possible note: I had to build a special (2.6.33.15) kernel because the K6-III+ CPU in the PI machine does not support PAE and CMOV. There could be kernel related issues involved. I have no problems with KDE3 and the 2.6.27.59 kernel, and that is a special kernel build too.

I ran Ark again on the PI box. This time I selected a small archive file. Ark opened but upon closing I received the crash dialog. Here is the backtrace created by that:

I had been opening the archived files from within Konquror. Curious, I opened the same archive file using KRunner. No crash with opening or closing Ark. I repeated both methods three times. Opening from within Konqueror resulted in a crash every time. I thought I was on to something but then on the third try with KRunner Ark failed to open and I received a crash. Here is the backtrace created:

I wish I knew how to read backtraces or at least deduce where the problem is lies. :)

I hope this additional information helps.

Closing as works for me. I no longer can replicate the bug.
