[TYPO3-english] Backslash added when saving TS Template

[Per Inge Håland]

I`m totally stuck.
Using Typo3 4.2.8 on hosted ISP.

When editing my TS Template I get a strange error, everytime I save a 
backslash is added before a " e.g:

temp.nav = HMENU
temp.nav {
   wrap = <ul id=\\\"nav\\\">|</ul>
   1 = TMENU
....

it is supposed to be:
temp.nav {
   wrap = <ul id="nav">|</ul>
   1 = TMENU
....

any idea on what might happened and how to get out of this situation?

Prvious to the occurance of the problem I tried to add the following code:
#Google webmaster admin
page.headerData.11 = TEXT
page.headerData.11.insertData = 1
page.headerData.11.wrap = <meta name="verify-v1" content="|" />
page.headerData.11.value = a-value-from-google

Thank`s in advance
