It's funny that while you were replying I was reviewing *that* commit and thinking, "why are all these tests failing now just because they changed to test_expect_equal_file"? > Carl, if you (or anyone else) understands what the issue is, then please > go ahead and modify the commit message.

New commit message below for reference. -Carl commit d5b4d950245605b84c56ce991fa3c59a073a70e5 Author: Jameson Graef Rollins <jroll...@finestructure.net> Date: Sat May 28 14:52:00 2011 -0700 show: Avoid inadvertently closing stdout GMime has a nasty habit of taking ownership by default of any FILE* handed to it va g_mime_stream_file_new. Specifically it will close the FILE* when the stream is destroyed---even though GMime didn't open the file itself. To avoid this bad behavior, we have to carefully set_owner(FALSE) after calling g_mime_stream_file_new. In the format_part_content_text function, since commit d92146d3a6809f8ad940302af49cd99a0820665e we've been calling g_mime_stream_file_new unconditionally, but only calling g_mime_stream_file_set_owner(FALSE) conditionally. This led to the FILE* being closed early when notmuch show output was redirected to a file. Fixing this fixes the test-suite cases that broke with the previous commit, (which added redirected "notmuch show" calls to the test suite to expose this bug). Edited-by: Carl Worth <cwo...@cworth.org> with a new commit message to explain the bug and fix.
