[evolution-patches] patch review for crash bug

[Calvin Liu <calvin liu sun com>]

Hi, there,

Here's a small patch to fix a crash bug.
If you create vfolder like "xxx%%$$" it'll crash  on solaris or
mis-displayed.
Suppose we shouldn't decode for all "%xx" case, the "x" here should be
{digital|a~z|A~z}.

Thanks.
Calvin
