If you extract files from a ZIP archive with Konqueror and there are some CRC errors, Konqueror ignores this. It extracts the (corrupted) files from the ZIP archive without are warning.

Comment 1 David Faure 2005-03-31 12:21:46 UTC

Can you attach a sample ZIP file with such a CRC error?

Comment 2 bastiaf 2005-04-03 00:12:20 UTC

Created attachment 10491 [details]
Sample file with CRC error

Simple ZIP file with CRC error.
A text file with the text "hello" was compressed and after this the ZIP was
modified (changed hello to Yello in zip-file). After this unzip warns with "bad
CRC", but Konqueror extracts the corrupt text file without a warning.

Comment 3 bastiaf 2005-04-03 00:16:16 UTC

I don't why the attachment filename is attachment.cgi, but it is the zip file.

Comment 4 Nicolas Goutte 2005-06-23 15:38:46 UTC

To comment #3: it is normal. KDE Bugs handles attachments through attachment.cgi.

Comment 5 FiNeX 2008-11-30 21:30:08 UTC

Even ark doesn't display any error. It happens on GNU/Linux too.

Comment 6 Fahad Alduraibi 2017-09-12 13:27:36 UTC

it is still a problem with Ark, i just extracted a file, and ark extracted half the content and finished without showing an error!

Comment 7 Julian Steinmann 2018-07-21 12:39:18 UTC

I can still reproduce this bug with KDE Frameworks v5.48 on KDE Neon Developer Edition, reassigning to kio-extras.
