Segmentation fault with simple lftpget example

[mxmlnkn]

gdb -ex r -ex bt --args sh $( which lftpget ) sftp://127.0.0.1:22:silesia.tar.gz .

Backtrace:

Based on the backtrace, it seems that I am using the command wrong? But the manual for lftpget is very sparse. An example would be nice.

The correct call seems to be lftpget sftp://127.0.0.1:22:/home/user/silesia.tar.gz. I have not found any possibility to specify a relative path. That would have been nice.
