The crash comes from the fact that you have previewed some file in the archive. Do you remember which one it was?

Yes, I would have been the META-INF/MANIFEST.MF

Thanks :)

Hmm, it doesn't seem to exist in the zip file you linked in the report.

(In reply to comment #3)
> Hmm, it doesn't seem to exist in the zip file you linked in the report.

O, yes, sorry - it's in a jar file in the zip. commons-beanutils-1.8.3.jar. I opened that with ark and previewed the /META-INF/MANIFEST.MF file

So you opened the original file, clicked the .jar file inside Ark and launched a new Ark instance and tried to preview that file?

It's weird that apparently Dolphin was used to preview this file. Can you still reproduce it? If you extract the jar, what program ends up being used to open that file?

Ok, so I just reproduced it now. I opened Dolphin to view the downloaded zip file. I then right-click on the zip and select open with ark. Then within ark I select the jar file (that then opens in another ark again). I then preview the MANIFEST.MF file. Then I close the preview, close the jar's ark and close the zip's ark, and then I get the error: (B.t.w it does not happen every time, so not easy to reproduce - I do open jar files often to inspect their MANIFEST.MF files to see if they are OSGi ready, so it see it often, it's not just the beanutils file)

Ok, I manage to recreate the bug every time now. Follow this instructions (also see desktop recording at http://dev.thumbtribe.co.za/phillip/ark_video.mp4)
1) Open folder containing zip file in Dolphin.
2) Right-click > open with Ark on the zip file.
3) Select the jar file in the ark window (that opens another ark)
3) Select the MANIFEST.MF in the new ark.
4) Go back to the original Ark and select the root folder.
5) Click extract (You can cancel the extract/ or actually extract the file)
6) Close the first (zip file) ark window (with the Jar file ark and MANIFEST.MF preview still open.
7) Tada ! Bug report pops up :)

Hope this helps.

Confirming, thanks for the detailed information.

Actually, if I leave out both steps 3 and step 5 I can still reproduce it (that is, the bug can be triggered by just previewing the top-level directory). The directory should not be previewable to begin with...

infozip itself seems to be identifying the attributes of the top-level directory incorrectly. I've sent a bug report to their forum and am waiting for a response.

For now, we might need a workaround on Ark's side.

Cool - So the preview was never the MANIFEST but the folder - that's why Dolphin is used. Ok, please let me know if I can help with anything else. Cheers.

clizip: Detect whether an entry is a directory in a dumber way.

infozip seems to have some trouble indentifying whether some entries
are directories in certain zip files, and outputs the wrong
information in the entry's attributes.

Simply checking if an entry's name ends in '/' seems to be more
reliable.

This also uncovered a crash in Dolphin, so I'm not closing the bug
right now.

The Ark side of the bug should be fixed in 4.7.1.

Alright, Ark's side should be fixed now.

I'm reassigning to Dolphin because dolphinpart should not crash at all. ppenz, I can reproduce the crash when using Dolphin v4.7.0, but master does not crash.
