--- Comment #25 from Anguo <kde_b...@overshoot.tv> --- OMG! Christoph! I can't believe the fix was so easy! I am so happy. :D At last I can make some sense of the tabs in my taskbar again! I don't know how long it took you to dig out the right method, but you certainly saved me days (at the very least) of hair-pulling on my side! Still, your time is at least as valuable as my own, so I greatly appreciate the help you provided! Now, on the technical side of things, I did two tests; the first one was not successful, the second was. The first time, I simply did what I mentioned above. I simply edited konqueror.desktop so that I had "Icon=" instead of "Icon=konqueror". I didn't log out nor reboot, but I started another session: there was no change. The second time, to be sure to stack the cards on my favour, I did 2 things. I hadn't found the definition of AppData::icon::isNull() so I didn't know if an empty string would count as Null. Thus, I completely deleted the "Icon=" line from the konqueror.desktop file. ALSO, I patched the file Christoph mentioned and recompiled the package, and installed it (within gentoo, that's all done with a single 'emerge' command), then rebooted the computer. After reboot, I was back in sanity land! Yeah! :D @artem, Please test the following and tell us if it works: do: $ locate konqueror.desktop On my system, I found this: /usr/share/kde4/services/konqueror.desktop Completely remove the Icon= line, save the file then reboot. See if it's enough to remove the regression and fix your system. The simplicity of the fix proves that the reasons given in #4 are complete bullshit. It'd take 30 minutes for an experienced Plasma developer to code a setting into systemsettings and look up that setting within XWindowTasksModel::Private::icon(WId). A warning could be provided for the user, warning them about low-resolution favicons, potential inconsistencies, etc.... none of which I experience at this happy hour. -- You are receiving this mail because: You are watching all bug changes.
