kdevplatform: crashes when compiling with svn plugin

[benjamin@…]

Steps to reproduce:

• project -> new from template...
• c++ no gui / simple cmake based c++...
• project name test
• no version control
• Finish
• OK

Below is the output of kdevelop:

I did take a look at the problem, but it seems slightly more complicated than what I thought at the beginning. Similar debug messages appear on a working install (Kubuntu, 11.04), where the project can nevertheless be created. Identifying the problem will thus take more analysis.

I had the same problem and after running it in gdb I could see it was crashing doing svn stuff. So I disabled the svn plugin and it now works. Maybe svn library mismatch? doesn't appear to be using the osx subversion library but maybe it compiled against it?

Thanks a lot for the input. I can indeed reproduce this behaviour. It seems however that the compilation correctly links to the macports version of subversion, as shown from the output of the configuration step:

-- Found subversion client lib: /opt/local/lib/libsvn_client-1.dylib
-- Found subversion repository lib: /opt/local/lib/libsvn_repos-1.dylib
-- Found subversion fs lib: /opt/local/lib/libsvn_fs-1.dylib
-- Found subversion subr lib: /opt/local/lib/libsvn_subr-1.dylib
-- Found subversion wc lib: /opt/local/lib/libsvn_wc-1.dylib
-- Found subversion ra lib: /opt/local/lib/libsvn_ra-1.dylib

In order to have a functioning version, I disabled the svn plugin in the Portfile in r89436. It could then be added as a variant if the problem can be solved.

This bug seemed to be due to a misuse of subversion version 1.7 ​https://bugs.kde.org/show_bug.cgi?id=284061, which is solved with kdevelop 4.3.0, committed in r90780.
