Comment 1 Nick Savoiu 2005-01-18 19:43:21 UTC

Dies the same way if I try to access the same file as a result of a double click in Classes.

Comment 2 Amilcar do Carmo Lucas 2005-01-18 19:52:29 UTC

Which QT version?

Comment 3 Nick Savoiu 2005-01-18 22:57:12 UTC

Qt 3.3.3

Comment 4 Alexander Dymo 2005-01-20 22:26:41 UTC

I can't reproduce the crash therefore I need more information:
1) if possible please send me files (both .h and .cpp) you use and have a crash with
2) if that #1 not work, please compile kdevelop with debug information (like ./configure --enable-debug=full) and post here the backtrace again.

Comment 5 Nick Savoiu 2005-01-25 06:27:29 UTC

Any file I try to open in that project kills KDevelop. It might be a corrupted project file.

I can't reproduce it with KDevelop 3.1.91.

Comment 6 Jens Dagerbo 2005-01-25 20:30:46 UTC

Well, if it doesn't happen with 3.1.91, then I guess we must assume it's been fixed. It's very unlikely that a KDevelop-3.1.3 will be released so in KDevelop-3.2 is the "solution".

Comment 7 Aleix Pol 2013-03-31 01:31:12 UTC

moving to kdevplatform's classbrowser
