           Summary: QIF import consumes all memory and is killed by OS
           Product: kmymoney4
           Version: 4.6.1
          Platform: Gentoo Packages
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: general
        AssignedTo: kmymoney-devel at kde.org
        ReportedBy: thebitpit at earthlink.net


Version:           4.6.1 (using KDE 4.6.5) 
OS:                Linux

Exported QIF file with account and Stock symbol information from Quicken.  
Imported this file to KMyMoney using the default built in database.  
KMyMoney showed a  progress bar that went to 100% then reset the bar and
started on the next part of the import.  It ran for a while, the system slowed
way down, then KMyMoney was killed by the OS.  

I changed KMyMoney to use MYSQL as the database.  
It does _not_ crash.
It took about 12 hours to complete the import of 50 categories, 30 accounts,
only 2 transactions as the transaction data was not exported, and a very large
number of stock prices for different dates on over 100 stocks.
This completed OK.

There appear to be 2 bugs.
1) KMyMoney does not manage memory properly when accessing the internal
database.
2) QIF import uses a very poor algorithm somewhere as it runs far too slowly.  

Reproducible: Always

Steps to Reproduce:
1) Export a QIF from quicken with account information and stock information for
data that has accumulated for about 15 years.  
2) Import QIF into a freshly installed KMyMoney.  


Actual Results:  
KMyMoney is killed by the OS after it uses all available memory.

Expected Results:  
Import of QIF should complete correctly.

NOTE: expected result was obtained when using a MYSQL database.


OS: Linux (x86_64) release 3.0.6-gentoo
Compiler: x86_64-pc-linux-gnu-gcc
