Indeed this has probably been fixed some time ago and the fix is on
0.9.5. But testing again would be useful.

w32: Fix crash due to bad conversions of utf-8 in the clipboard. * src/gpgmetools.c (dos_to_unix): Remove. Remove all calls. (dump_data_to_clipboard): Return an error code instead of calling exit. * src/gpaexportclipop.c (gpa_export_clipboard_operation_complete_export): Print success message only on success. -- The removal of dos_to_unix is possible due to the patch https://bugzilla.gnome.org/show_bug.cgi?id=649390 which will go into the next Gtk+ 2.24 version.dos_to_unix was anyway not correct because it scanned for an embedded nul but it is not guaranteed that it is always called with one. The other patch which will be helpful is: https://bugzilla.gnome.org/show_bug.cgi?id=696232 (g_utf8_to_utf16() is not guaranteed to succeed. Check the error and return if it failed.) Gpg4win uses both patches. GnuPG-bug-id: 1525
