my recommand is update your gimp to 2.2.17
someday ago, I worked with psd file using 2.2.17. there was no problem.
if you can't open still, please install 2.3.19 developer version.
== 2.3.19 ==
- support long layer names in PSD files
== 2.3.8 ==
- made PSD load and save plug-ins 64bit clean
- added basic support for layer masks to the PSD save plug-in
== 2.3.0 ==
- improved PSD save plug-in
