[Bug 803619] [NEW] KDevelop stops accepting text input

[Thucydides411]

Public bug reported:

While working on a c++ project, KDevelop works fine for the first few
minutes after opening. After a few minutes, the cursor stops blinking,
and the user can no longer input text into - nor delete text from - any
of the open files. This happens at seemingly random times, but
frequently. The only sure workaround I have found is to close KDevelop
and restart the program, although sometimes after leaving KDevelop alone
for a while, it begins working again.

Running KDevelop from a terminal, here is the output I get when the
cursor stops blinking:

kdevelop(7519)/kdevplatform (language) KDevelop::TopDUContextDynamicData::getDeclarationForIndex: declaration index out of bounds: 1725 count: 18 
kdevelop(7519)/kdevplatform (language) KDevelop::TopDUContextDynamicData::getDeclarationForIndex: declaration index out of bounds: 1725 count: 18 
kdevelop(7519)/kdevplatform (language) KDevelop::TopDUContextDynamicData::getDeclarationForIndex: declaration index out of bounds: 1725 count: 18 
kdevelop(7519)/kdevplatform (language) KDevelop::TopDUContextDynamicData::getDeclarationForIndex: declaration index out of bounds: 1725 count: 18 
QVariantMap DBusMenuExporterDBus::getProperties(int, const QStringList&) const: Condition failed: action 
execute composite (NativeAppJob(0x5cbc100, name = "MCMC Lightweight") )

The line about "declaration index out of bounds" happens repeatedly as
the program runs, but it seems that the "Condition failed: action" is
associated with the bug.

I am running 64-bit Ubuntu 11.04 with Unity. The installed version of
KDevelop is 4:4.2.2-0ubuntu2, from the natty/main amd64 repository. I
can provide any other necessary infomation related to the bug.
