Bug 548676 – x11-misc/shared-mime-info-1.4: broken 'iso' files

• Product: Gentoo Linux
• Status: RESOLVED FIXED

[Description i.Dark_Templar 2015-05-05 11:24:09 UTC]

Problems with shared-mime-info lead kmimetypefinder to not recognizing some of hybrid iso images. Upstream should fix it in next release of shared-mime-info.

Reproducible: Always

Steps to Reproduce:
1. get usual and hybrid iso images
2. check their mime types via kmimetypefinder (kde-base/kmimetypefinder) or use Dolphin (kde-base/dolphin).
Actual Results:  
'application/x-cd-image' for usual iso images and 'text/plain' for most of hybrid iso images

Expected Results:  
'application/x-cd-image' for all iso images

For tests i've downloaded xubuntu-15.04-desktop-i386.iso from http://xubuntu.org/getxubuntu/. I guess using other images from that page would provide same results.
I've also downloaded FreeBSD-10.1-RELEASE-i386-bootonly.iso from ftp://ftp.freebsd.org/pub/FreeBSD/releases/i386/i386/ISO-IMAGES/10.1/
I have also already had some other images, including Gentoo install and livedvd ones.
Mime types are recognized more or less fine via "file --mime-type $filename" (application/x-iso9660-image), "mimetype $filename" (application/x-gamecube-rom), and "xdg-mime query filetype $filename" outside KDE session (it fallbacks on mimetype or file methods, while in KDE session it uses kmimetypefinder, which is affected)

Test results for kmimetypefinder:
$ for i in *.iso ; do echo -n -e "\n$i:\t" ; kmimetypefinder $i ; done
