Description Nicolas L. 2008-12-23 13:20:38 UTC
Version:            (using Devel)
Installed from:    Compiled sources

Test done with kde 4.1.85

if i add Amarok in the audio/ogg mimetype, the ~/.local/share/applications/mimeapps.list file is writen like this: 

[Added Associations]
\naudio/ogg=kde4-amarok.desktop
Comment 1 David Faure 2008-12-23 20:16:35 UTC
This one really puzzles me. Do you see \n in any other config file? (~/.kde[4]/share/config/*)
Comment 2 Nicolas L. 2008-12-23 20:44:35 UTC
yes i have some in /home/test/.kde4/share/config/filetypesrc

its content is like this :

Comment 3 David Faure 2008-12-23 21:58:21 UTC
So this is about mimetypes again, not a KConfig bug.

Does "kmimetypefinder foo.mp3" answer
audio/mpeg
(accuracy 100)

or is there a newline (a real one this time, I think), before audio/mpeg?
Comment 4 Nicolas L. 2008-12-23 22:03:26 UTC
i obtain this : 

$ kmimetypefinder foo.mp3
audio/mpeg
(accuracy 100)
Comment 5 Nicolas L. 2008-12-24 00:33:45 UTC
i started to add the nonewline patch you gave me  ( the one that apply on apps/ )
now i can go on the file association part anymore ( i removed /home/test/.kde4/share/config/filetypesrc  and ~/.local/share/applications/mimeapps.list  but this is  the same.

Comment 6 Nicolas L. 2008-12-24 01:35:30 UTC
the patches applied for the debuging are : 
http://web.davidfaure.fr/tmp/nonewline.diff
http://web.davidfaure.fr/tmp/kopenwithdialog-nonewline.diff
Comment 7 David Faure 2008-12-24 11:44:01 UTC
Good, getting somewhere.
I made a separate test program to understand where this comes from - please unpack, then
cmake . && make && ./kallmimes

If it asserts, then the bug is in kbuildsycoca4. Uncomment this debug output in kded/kbuildmimetypefactory.cpp:
     kDebug() << "Creating mimetype" << name << "from file" << file << "path" << fullPath;
and add this line after it:
    Q_ASSERT(!name.contains('\n'));
Rebuild, then run kbuildsycoca4 --noincremental, and tell me if it asserts.

If kallmimes works fine then, hmm, I'm even more puzzled and the bug is in the filetypes editor.

Comment 9 Nicolas L. 2008-12-24 12:44:55 UTC
ok it assert with it

ASSERT: "!mimetype.contains('\n')" in file /home/neoclust/rpm/BUILD/testprogs/kallmimes/kallmimes.cpp, line 39

i am rebuilding my kdelibs with the kdebug and the assert you asked.
Comment 10 Nicolas L. 2008-12-24 12:45:54 UTC
this is how this is in the konsole  :
"video/x-flic"
"audio/x-ape"
"application/sieve"
"
video/x-mpeg2"
ASSERT: "!mimetype.contains('\n')" in file /home/neoclust/rpm/BUILD/testprogs/kallmimes/kallmimes.cpp, line 39

nspluginscan bug, please test  http://www.davidfaure.fr/tmp/pluginscan.cpp.diff

\o/

now i obtain :

Comment 13 David Faure 2008-12-24 14:30:03 UTC
OK, for the record, the bug was in the NP_GetMIMEDescription implementation of /usr/lib/mozilla/plugins/mplayerplug-in.so, which returns mimetypes separated by ";\n" instead of just ";" as specified by https://developer.mozilla.org/En/NP_GetMIMEDescription

Let's have the workaround, anyway, can't hurt.
Comment 14 David Faure 2008-12-24 14:31:18 UTC
SVN commit 901122 by dfaure:

Don't generate mimetypes like "\nvideo/x-mpeg2" -- the bug was in the NP_GetMIMEDescription implementation of
/usr/lib/mozilla/plugins/mplayerplug-in.so, which returns mimetypes separated by ";\n" instead of just ";" as specified by
https://developer.mozilla.org/En/NP_GetMIMEDescription... Nicolas will report that bug, but let's have the workaround
anyway, can't hurt.
