The problem is:

comctl32: cchTextMax in TVN_ENDLABELEDIT should be the full buffer size

In Password Safe, when the user edits a tree view label, and removes
    brackets, the application wants to restore the original, longer
    string. It does this by editing pszText within the TVITEM.
    It determines the length of the buffer from cchTextMax. Windows passes
    260 and all is well. Wine passes strlenW(pszText)+1, which is of
    minimal length, and trying to copy a longer string into it causes
    the MSVC runtime to falsely detect a buffer overflow and raise
    an exception, crashing the application.

Let's pass 260 like Windows.
