[gmime-devel] Issue with header decoding (continues)

[evil legacy <evil legacy gmail com>]

Hi, 

After more debugging, I found that the problem is when iconv (cd, NULL, NULL, &outbuf, &outleft) tries to flush the buffer to outbuf, but outbuf isn't big enough to hold it.

This little patch to the charset_convert function seems to fix this problem (works for me):

<patch>

</patch>
