[Bug 447] New: Several crashes using ctaskbrowser (CORBA)

For more infomation about this bug, visit
Summary: Several crashes using ctaskbrowser (CORBA)
Product: RTT
Version: 1.2.1
Platform: All
OS/Version: All
Status: ASSIGNED
Severity: normal
Priority: P2
Component: Corba
AssignedTo: orocos-dev [..] ...
ReportedBy: peter [dot] soetens [..] ...
CC: orocos-dev [..] ...
Estimated Hours: 0.0

It appears the CORBA enabled taskbrowser suffers from crashes from bad memory
management in the CORBA proxy (client-side) code of the RTT. Since the
KTaskbrowser only uses the server-side code of the RTT, these got unnoticed for
a while. I'm fixing these as I'm testing it against a complex application.
