hadess, thanks for reporting :)

AFAIK, it's a unzip bug. Unzip has three wildcard expressions:

*      matches a sequence of 0 or more characters
 ?     matches exactly 1 character
[...]  matches  any  single  character  found inside the brackets; ranges are
       specified by a beginning character, a hyphen, and an ending character.
       If  an  exclamation  point  or  a  caret (`!' or `^') follows the left
       bracket, then the range is  complemented.

If  no matches are found, the specification is assumed to be a literal filename.

Evince uses the following command for decompressing the pages:

unzip -p -C -- '/path/file.cbz' 'path/page.jpg'

we have the problem only with the page component and it only happens if 
the page component has the character '['

About the workaround, I can escape  '[' with '\[', but I've realised that if 
you 
use '`' for quotation instead of ''', provided by g_shell_quoation() unzip

unzip '/home/jjmarin/Desktop/[foobar.cbz' '\[foobar/1.jpg'
unzip '/home/jjmarin/Desktop/[foobar.cbz' `[foobar/1.jpg`

The second one is the most generic solution and requires less computing.

Well, what just after writing the comment I've realised it's not complete true. 
I will write a better analysis later on

Hi, I come up with a fix for the regex problem with unzip. Unzip accepts regex 
expressions for both the zip file and for the files compressed in the file.

Another related issue is that unzip -Z -l , used for listing the files included 
on the cbz file, doesn't handle encoding filenames properly and it turns 
unhandled characters into '??', that is a regex expression. I found out we can 
use zipnote to get the list of files correctly encoded, or at least I haven't 
found any problem so far.

So, listing the files with zipnote I can disable all the regex expression 
accepted by unzip (*,? and []). The funny thing is that I use the regex 
expression [] for disabling :)

Fix a memory leak and removes regex quotation for zipnote

Pushed to git master and gnome-2-30. Thanks!

Hi,

this patch breaks cbz support for all the cbz files on my system. All I get is a red bar claiming that evince doesn't support the application/x-cbz mimetype and an error message in console:

zipnote error: Invalid command arguments (can only specify one zip file)

I reverted it and the cbz files work again. I have zip 3.0 and unzip 6.0 here.

Thanks Giacomo, I _really_ appreciate your feedback !

The patch was a little bit tricky and I overlooked a fundamental detail: to quote the input for zipnote. I attach an incremental patch for fixing this. 

More feedback for the new cbz code will be welcome !

g_shell_quote() for zipnote

Reopening, as it's still broken :)

I suspected something like that but didn't have the time to delve into the code. Anyway, your last patch fixes the bug here, thanks.

Applied to git master and gnome-2-30 branch and released 2.30.3
