Failed to write to process: Error writing to process | fatal: Empty path component found in input

[valarion]

removing the option --svn-ignore solves the problem, but I have to create the gitignore manually

[eeijlar]

Did it generate a core dump?

[valarion]

Only a stackdump, that I can find:

If you need more information let me know.

I already fixed the handling of .gitignore in the root directory in 60bfc16 and some other gitignore related bugs.
1.0.18 should not have this issue.
