Error reading tag from Photomechanic

[LaptopHeaven]

Ran into an issue working with certain images exported from photomechanic.
Looks like it's appending multiple null values to the end of the XMP data.

I was able to pinpoint the problem and fix it here.

taglib-sharp/src/TaglibSharp/Xmp/XmpTag.cs

Line 261 in c853d26

if (data[data.Length - 1] == '\0')

From
if (data[data.Length - 1] == '\0')

To
while (data.Length > 0 && data[data.Length - 1] == '\0)

I ran into the same problem, debugged it, solved it and then found this issue, which came up with the same solution.

In my case I had to remove more than 1000 '/0' from the string. Because of that, I changed the code slightly, to avoid creating 1000 strings:

if (data[data.Length - 1] == '\0') {
    int shorterLength = data.Length - 1;
    while (shorterLength>0 && data[shorterLength] == '\0') shorterLength--;
    data = data.Substring (0, shorterLength);
}
