[Evolution] What file is this? (Crash while evolution was running)

[FunFlyer gmx net]

Hello,

sorry for bothering, but I got a problem I'm sure is quick to solve:

About an hour ago, my computer froze when I was just starting evolution. Unfortunately, after a re-boot 
evolution wants me to set up my email accounts anew. 

I've figured out that's due to a configuration file missing that I discovered in the lost+found folder. It 
starts like this:

--snip-->

[Store mbox:/home/my_user_name/.evolution/mail/local]
Expanded=true

[Store vfolder:/home/my_user_name/.evolution/mail/vfolder]
Expanded=true

[Search Bar]
SearchScope=mail-scope-current-folder
SearchOption=mail-search-subject-or-addresses-contain
SearchFilter=mail-filter-all-messages

[Folder mbox:/home/my_user_name/.evolution/mail/local#Inbox]
Expanded=true
GroupByThreads=false
SearchFilter=mail-filter-all-messages
SearchOption=mail-search-message-contains
SelectedMessage=21731

[Folder Tree]
Selected=folder://1316120998.2597.2[removed for privacy]

[Folder mbox:/home/my_user_name/.evolution/mail/local#Sent]
GroupByThreads=true
SearchOption=mail-search-subject-or-addresses-contain
SearchFilter=mail-filter-all-messages
SelectedMessage=1039

<--snap--

It goes on like this for some time.

Could you please tell me the name of this file and where to put it so evolution (3.2.3) finds it again? I 
couldn't find anything on this on google. 

Best regards & thanks for your time
Lennart
