Bug Description


Firstly, thank you for maintaining Calibre packages!

It seems that Calibre's launcher is named 'calibre.desktop' but when you launch Calibre GUI, you can see that Calibre window's class is 'Calibre-gui' and not 'Calibre'. (according to `xprop`)

It's maybe a detail but if the name of the class and the launcher are different, it's harder for a taskbar manager (a shell, a panel, a dock, etc.) to make a link between them.

In the source code of Calibre, I see that it should produce a launcher named 'calibre-gui.desktop':
But it seems that Debian/Ubuntu packages are using their own launcher:

Is it possible to use the upstream launcher or to rename Debian/Ubuntu's launcher? (note that it's also maybe better to have an icon with the same name as the launcher => )

@Martin: Thank you for this quick fix :)

It's actually not that quick -- renaming the .desktop lost the icon entirely, at least in Unity. I need to look into this.

It's maybe better to rename the icon too:

    - cp manual/resources/logo.png debian/tmp/usr/share/pixmaps/calibre.png
    + cp manual/resources/logo.png debian/tmp/usr/share/pixmaps/calibre-gui.png

    - Icon=calibre
    + Icon=calibre-gui

But why not using .desktop files from upstream? :-)

I've only seen this problem with Python apps. Is there an underlying bug in python-gobject?

Never mind, gparted isn't a Python app which disproves my theory.

I renamed the icon to "calibre-gui" as well, works fine here in Unity.

calibre (0.9.41+dfsg-1) unstable; urgency=low

  * New upstream release.
  * debian/local/calibre.desktop: Rename to calibre-gui.desktop to match its
    window class. (LP: #1206687)
  * Add debian/local/ebook-viewer.desktop, so that one can directly open
    *.epub or *.mobi files in file browsers. Thanks Korey Lu!
    (Closes: #664182)
  * Make it possible to auto-start calibre when connecting an e-book reader
    - Add debian/local/mime/calibre.xml MIME association, install in
    - debian/local/calibre-gui.desktop: Add MIME type and file argument.
    - Thanks to Thanks Korey Lu! (Closes: #715246)
