Sentry Crash Report:

Description Ygor Mutti 2014-12-18 12:14:54 UTC 
I'm trying to import a C# project (closed source) into Umbrello using the "import project" option, but I can't because it crashes during the import process.

Reproducible: Always

Steps to Reproduce:
1. Open the "Code" menu, then the "Active language" submenu and click C#.
2. Open the "Code" menu, then click the "Import project..." command, select the directory containing the C# project and click the "OK" button.

Actual Results:  
I can see some classes from the project are imported looking at the Command history panel, then Umbrello crashes.

Expected Results:  
Do not crash and import the project.

The backtrace 
>#8 0x00007ffaf1530e14 in __libc_message (do_abort=do_abort@entry=1, fmt=fmt@entry=0x7ffaf163f5a8 "*** Error in `%s': %s: 0x%s ***\n") at ../sysdeps/posix/libc_fatal.c:175

indicates a memory corruption somewhere in members storage of class NativeClassImport, but from the backtrace only there is not enough information to get an idea where the root cause may be.

Any chance to recheck a newer version of umbrello ? 

I tried the following public available c# sources with 2.13.3 and got crashes too 

https://subtext.googlecode.com/files/SubText-2.5.2.0.src.zip
http://sourceforge.net/projects/nant/files/nant/0.92/nant-0.92-src.tar.gz/download

but not with 2.14.2.

Another option would be to provide the related sources or, if not possible, a c# test case with which the problem could be reproduced.
