sometimes drkonqi endless prompts to [Install Debug Symbols] and is never satisfied

[skierpage]

I'm running Kubuntu 12.04 alpha2 amd64 with all the daily System Updates.
Qt: 4.8.0
KDE Development Platform: 4.8.00 (4.8.0
The KDE Crash Handler: 2.1.5

Sometimes the KDE Crash Handler runs. I try to help, so I click [Report Bug]. Then the KDE Crash Reporting Assistant pops up, takes time generating a backtrace, and says "The generated crash information is probably not useful". So I click [Install Debug Symbols]. After entering password to install debug libraries, eventually it goes back to Fetching the Backtrace.

This is all fine. But in several situations, I'm back to "The generated crash information is probably not useful" and the button to [Install Debug Symbols]. And if I click the button I never progress!

The most recent example was a crash in apport-kde itself, see bug #948656. If I click the link (_list of files_) I get a dialog
  The packages containing debug information for the following application and libraries are missing:
  * /usr/bin/python2.7

but
a) I have python-dbg Version: 2.7.2-9ubuntu2 installed
b) I know I've got stuck in this endless loop before

Expected results:
drkonqi should realize the user has installed the debug packages and it's still not a useful backtrace and so STOP with something like "The crash information is still not useful, but thanks anyway. _Reason_" (and if you click on _Reason_ it says "Can't get debug information for xxx")

Status changed to 'Confirmed' because the bug affects multiple users.

I've been trying to run drkonqi manually to connect to a running kate, and getting the same sort of problem. E.g.,

$ /usr/lib/kde4/libexec/drkonqi --pid 23327 --bugaddress <myemailaddress> --signal 1 --appname "appname" --programname "programname" --apppath "/appath" --appversion "appversion"

I can view the stacktrace, though "The generated crash information is not useful." When I click "list of files" (under "install the needed packages (list of files) and click the /Reload/ button."), a dialog appears: "The packages containing debug information for the following applications and libraries are missing: /usr/bin/kate", but I have already installed kate-dbg. Just the same I have tried "Install Debug Symbols" which presents a progress dialog for a while, then generates a new backtrace (the same as the existing one). There is console output at this point:

87 ../sysdeps/unix/sysv/linux/poll.c: No such file or directory.

The generated trace follows, and the only ?? appearances are for libQtScript (for which there don't seem to be debug packages). I'm not sure which packages drkonqi actually wants to install, nor why.

Sorry, should have included some system information:

$ /usr/lib/kde4/libexec/drkonqi --version
Qt: 4.7.4
KDE Development Platform: 4.7.4 (4.7.4)
The KDE Crash Handler: 2.1.5

$ uname -a
Linux ubuntu 3.0.0-14-generic #23-Ubuntu SMP Mon Nov 21 20:28:43 UTC 2011 x86_64 x86_64 x86_64 GNU/Linux

And I've just update and dist-upgraded.

I believe I've stumbled accross the same problem with Kubuntu 15.04, but I've reported it to drkonqi tracker (where it has been closed by now) https://bugs.kde.org/show_bug.cgi?id=346545

I still find it surprising that the installer fails to install kdelibs5-dbg
