ubuntu-bug tomcat7 is crashing with "permission denied"

[Michael Basse]

On Ubuntu 12.04 i wanted to report a bug against tomcat7, so i used "ubuntu-bug tomcat7" and i got this traceback:
The first two german lines are just "collecting information can be send to the developers to improve the application"

As an additinal info:
i used "ubuntu-bug tomcat7" directly after the installation, so i did not change aynthing.

michael@raidbuntu:~$ ls -all /etc/tomcat7/tomcat-users.xml
-rw-r----- 1 root tomcat7 1530 Feb 25 2012 /etc/tomcat7/tomcat-users.xml

So seems like, ubuntu-bug is executing it as my normal user "michael" which is not part of tomcat7 or root.

michael@raidbuntu:~$ id michael
uid=1000(michael) gid=1000(michael) Gruppen=1000(michael),4(adm),24(cdrom),27(sudo),30(dip),46(plugdev),111(lpadmin),112(sambashare)

I think this is likely an issue in apport rather than in tomcat7. Changed package to reflect that. Will test later to determine the reproducibility of this issue.

[Quinn Balazs (qbalazs)]

Confirmed. "sudo ubuntu-bug tomcat7" works as expected as it supersedes any other permissions.

Confirmed this issue on gdebi-kde package

UPDATE: Taking closer look to the bug I find out that it's isn't really my issue.

[Quinn Balazs (qbalazs)]

This issue, as I am assuming you've realized, is specific to a problem in the apport hook for tomcat 7. If you're experiencing a similar problem with another package it should be filed as a new bug against apport.

Thanks.
