Version: 1.5.3 (using KDE 3.5.4, Gentoo) Compiler: Target: x86_64-pc-linux-gnu OS: Linux (x86_64) release 2.6.17-beyond2.2 Hi, I'd like to be an Umbrello poweruser since I sometimes need UML for my daily job. But I must admit it's unusable! It crashes every 10 clic! I suggest you to use valgrind to discover how many problems are in its code. Sorry being a bit rude. But 4 crashes in half an hour is too much :-)
Created attachment 17226 [details] Valgrind output just for opening and closing umbrello
AFAICT your valgrind log does not show anything directly attributable to the Umbrello source code (look more like problems in X and/or Qt.) I suspect you have enabled "Use new C++/Java/Ruby code generators" in the Umbrello general settings? Then this is a duplicate of #84739. Please update to umbrello-1.5.4 where this feature is disabled.
