[gentoo-user] OT - ImageMagick Strange Behaviour

[Colleen Beamer]

Hello All,

I wanted to edit a graphic today using ImageMagick.  I haven't used
ImageMagick in a while and recently, I did a bunch of mucking around
with my system (upgrade to KDE 3.5  where kaudiocreator started
exhibiting weird behaviour, then downgrade to KDE 3.4.3 and in the
course of this, I removed anything that had been installed in a new
slot, but I suffered no repercussions afterwards).

When I right-clicked on the graphic that I wanted to edit and chose
"open with" and display, ImageMagick didn't launch, but the
configuration screen for KRandRTray (the KDE screen resize and rotate
utility).  When I noticed this, I thought that maybe it was my mistake,
so I unmerged ImageMagick.  After doing this, I checked /usr/bin and no
executable named "display" existed.  When I emerged ImageMagick again,
the display executable was back in /usr/bin and exhibited the same
behaviour as explained above when I tried to launch ImageMagick to edit
the graphic.  This occurrence was on my desktop.

Over the past couple of days, I have been updating my laptop.  Since I
didn't want any slotted occurrences of packages, I removed all packages
that would have resulted in new slots being created - xorg-x11,
kde-meta, etc.  Then I emerged them again.  Everything seems fine. 
However, as I was keeping tabs on the progress of the 272 package
install of kde-meta, I noticed a couple of lines during different
compiles that said something to the effect "seems to have been relocated".

So, I'm wondering has anyone noticed the behaviour described above with
ImageMagick and could there have been a problem with the header used to
compile the program.  (Don't laugh, I'm not a programmer, but am taking
a stab! :-) )

Regards,

Colleen

Hmm... it does that here too.  Typing, instead of 'display', things 
like 'background', 'desktop' or 'mouse' opens the corresponding 
KControl module.  Apparently "Open With" and "Alt+F2" check the 
given command to see if it contains the name of a KControl module, 
and launches it when found.  Being KDE, this should be configurable 
I guess, but who has an idea where to look?

A workaround is to make a symlink, for example:
  ln -s display /usr/bin/show
and then invoke ImageMagick with 'show'.

A more radical workaround would be to unmerge kcontrol, but I 
haven't tried this.  :)

This seems like a bug in KDE: it should definitely skip checking for 
a KControl module name when there is a slash in the given command.  
Does anyone have an ideas where to start looking in KDE's mountain 
of code for this module-name check (to be able to provide a patch 
together with the bug report)?
