uSync Startup YSOD

uSync

Umbraco 7
Hey,

I'm getting an error with uSync at startup after uploading the usync folder to our dev server. The error is:
```
Sequence contains more than one matching element
```
Looking at the log files it comes just after Running Import for DocumentType:
```
2016-04-12 16:31:56,782 [P10652/D4/T1] INFO  Jumoo.uSync.BackOffice.Logging - Running Import: DocumentType
 2016-04-12 16:31:57,369 [P10652/D4/T1] ERROR Umbraco.Core.CoreBootManager - An error occurred running OnApplicationStarted for handler Jumoo.uSync.BackOffice.uSyncApplicationEventHandler
System.InvalidOperationException: Sequence contains more than one matching element
```
I've tried updating to the latest uSync package and then running a fresh export but still get the same error.

Slightly separate issue, after the upgrade to the latest uSync packages i've noticed it seemed to delete the content.config for my root node (Home) after doing the full export and doesn't seem to generate it again even if i save and publish the home node.

Cheers, Tom

Hi

could you add debug logging to the server and see if their is any intermediate logs

if you add
```
  <logger name="Jumoo.uSync">
    <level value="Debug" />
  </logger>
```
To the logging section of config/log4net.config you shoud get more logging to help us pinpoint the error.

Morning Kevin... Me again lol

I just removed the data folder temporally just so i could get into Umbraco and i noticed there was an empty Events doctype which there should only be an Events Folder, so not sure if this was human error or an issue with one of previous version of uSync. Anyhow after deleting that and putting the data folder back in it all worked okay :D

Thanks for getting back to me so quickly though.

Cheers,

Tom

no worries,

but just so i can track it down (and at least not have it YSOD) I am guessing

you have a folder called pages, with another folder called events in it ? and before the error you also had a doctype called events in the same pages folder ?

If that's true I am reasonably confident I can recreate and then fix that.

Hi

For reference, I think i have fixed this (so it doesn't happen when their is a doctype/datatype/mediatype with the same name as a folder).

https://github.com/KevinJump/uSync/commit/72d78163dea51dbd4dddc9a20c1307ce49563dc0

I will bundle it up in the next release.

Hi Kevin,

Yeah thats correct:

Pages (Folder)
    Events (Folder)
    Events (DocType - Although not sure where this came from as i don't recall creating it and it was just blank)
