            Bug ID: 114716
           Summary: LibreOffice Extension manager locks up, LO consumes
                    all available memory when pressing "Check for updates"
           Product: LibreOffice
           Version: 5.4.4.2 release
          Hardware: x86 (IA32)
                OS: Mac OS X (All)
            Status: UNCONFIRMED
          Severity: normal
          Priority: medium
         Component: Extensions
          Assignee: libreoffice-bugs at lists.freedesktop.org

Description:
When summoning "Extension Manager" and pressing "Auf Updates prüfen" ("Check
for Updates"), Extension Manager no longer reacts to User Interactions like
clicking on "Schließen" ("Close") in it's dialog.

Also, I see that LO's memory consumption then keeps growing until eventually it
takes all the available memory, bringing down the Computer as a result.

The only way I have found to stop this is force-quitting LO from OS X's
Activity monitor.

The same problem occurs when I double-click an OXT file in the Finder (I tested
this with LanguageTool-3.9.oxt) -> LO opens in the Extension Manager, displays
"Füge LanguageTool-3.9.oxt hinzu" ("Add LanguageTool-3.9.oxt"), then the
Extension Manager locks up & consumes memory as described above).

Steps to Reproduce:
1. Open LO
2. Create new Text document
3. Open Extension Manager
4. Click "Check for Updates"


Actual Results:  
Extension Manager locks up, LO memory footprint keeps growing until OS X is out
of memory

Expected Results:
Extension manager should show new/updates extensions.


Reproducible: Always


User Profile Reset: Yes



Additional Info:
I have experienced this issue also on previous 5.4.x versions of LO.
