Copy & Paste long text on Edit Data crashes

[Hexaae]

Describe the bug
Copy & Paste causes crashes on a .bundle extracted in memory (CAB-xxxxxxxxxxxxxxxxxxxx), if you Edit Data

To Reproduce

1. Open a .bundle
2. Click "Info"
3. Select a Monobheaviour file
4. Click "Edit Data" button (will warn the file is huge)
5. Copy & Paste edited text into the Edit Data window (I edit the text with an external editor like 010 Editor or Cudatext...)
6. Save clicking "Ok"
7. "Save As..." the .bundle
8. repeat from point 2 to 5 (paste the changed text again)

At this point, right after paste, UABEA will crash with this error:

System.NullReferenceException: Object reference not set to an instance of an object.
   at TextMateSharp.Model.TMModel.InvalidateLine(Int32 lineIndex) in /_/src/TextMateSharp/Model/TMModel.cs:line 429
   at TextMateSharp.Model.TMModel.TokenizerThread.ThreadWorker(Object state) in /_/src/TextMateSharp/Model/TMModel.cs:line 109

   at System.Threading.ThreadPoolWorkQueue.Dispatch()
   at System.Threading.PortableThreadPool.WorkerThread.WorkerThreadStart()
   at System.Threading.Thread.StartCallback()

Expected behavior
Nothing. Eeverything should go on as expected... It crashes instead.

Bug exists in the latest version of TextMateSharp. I'll report the bug to that repo later.
