Title:
Magic for text/x-tex broken
Status in shared-mime-info package in Ubuntu:
Fix Released
Bug description:
The magic for text/x-tex in Ubuntu 15.04 is broken as it assigns
text/x-tex to any text file which contains the word "section",
"chapter" or "documentclass" within the first 100 characters.
This behavior is fixed if one adds backslashes to the appropriate
match values in /usr/share/mime/packages/freedesktop.org.xml (.in)
(see attached patch).
Edit: You can reproduce this bug as follows.
Is (output on Ubuntu 15.04):
user@host:/tmp/mime$ dpkg -s shared-mime-info | grep "Version"
Version: 1.3-1
user@host:/tmp/mime$ sed '30568,30638!d' /usr/share/mime/packages/freedesktop.org.xml
