I use konsole as my IDE. I currently have four windows opened and about a dozen or so tabs on each window. I generally use the keyboard to navigate between each window/tab. Today, I clicked the minimize button on each of the tabs (attempting to get to the desktop to fix a application link). When I pulled all of the windows back up, every window had been renamed to the default "shell %#". This is not really what I would expect. I have no way to know what I did to make this happen, no way to repeat this (I HOPE!!!), and no clue of any special events that may have caused it. Reproducible: Didn't try
Which text was wrong? The text on the tabs or on the window title? Your bug report isn't really clear on this.
This is a really old report, so closing; reopen if the bug still happens.
