--- Comment #3 from Ralf Habacker <ralf.habac...@freenet.de> --- To be able to get some more informations it would be nice if you would download and install drmingw from https://github.com/jrfonseca/drmingw. Additional to get symbols it is required to download umbrello debug symbols with the same architecture as installed umbrello from http://download.kde.org/stable/umbrello/2.21.2/win32/ (debug symbols are in the *debug.7z packages) and unpack them in the umbrello install root e.g. the directory where the bin dir is located) Now you can run umbrello and if it crashes drmingw will open a related windows. Please copy and paste this content to this bug. To get even more informations you can download dbgview from https://download.sysinternals.com/files/DebugView.zip. Unpack the file and start dbgview before starting umbrello. It will reports umbrello's internal debug messages. -- You are receiving this mail because: You are watching all bug changes.
