OK, this is extremely wierd, and extremely reproducible. 1. I start up Umbrello, and make 2 classes, A and B. 2. I add 2 attributes of type B to a, resulting in 2 Composition arrows pointing from A to B, as expected. 3. I try to drag the lines of the arrows to try to re-route them, or do anything remotely involving the Compositions question. 4. Hang at 100% CPU usage. All other types of arrows have no problem... Also, this does not happen if there is only one Composition arrow. It seems there is only a problem if there are 2 or more Composition arrows coming from class A to class B. This happens in KDE and Gnome, and works like clockwork. Why does such a simple thing cause a crash? I'm not being mean here, I just would like to know what is strange about my system that causes this very specific bug... Anyways, the program has never recovered from such a crash, and has cost me quite a lot of time and lost work... Not to mention I cannot complete my assignment (for my class) because I can't have multiple Composition arrows... arrgh... Reproducible: Always Steps to Reproduce: 1. Start Umbrello 2. Make 2 classes, say, A and B. 2. Add 2 (or more) attributes of type B to A, resulting in Composition arrows pointing from A to B, as expected. 3. Drag the lines of the arrows to try to re-route them, or click anywhere near the arrows, or try to modify any parameters involving the Compositions. 4. Hang at 100% CPU usage.

have you reported this to the Umbrello developers at bugs.kde.org? Sounds like an issue they might need to know about.
Also look at bug 164174, it might be related?
I assume this is with umbrello-3.5.5? Have you tried umbrello-3.5.6?
Yes, this is with 3.5.5. I have not tested with 3.5.6, as that would require me using the ~amd64 version of kdelibs, which I don't have time to do right now (I use GNOME, the only reason I even have kdelibs is to run umbrello, as it is critical for my work). I'll post more info when I do have time. I have looked at the other bug, and it does strike me as similar. However, that one results in a outright crash, as I understand it. This problem simply results in an infinite loop of sorts.
Could we please make this bug with NEEDINFO.
Rather I'd like to ask Giacomo if he could paste his `emerge --info' again together with the results of testing 'umbrello' on version 3.5.6.
