Thank you for your comment, Caroline ! Sorry for this late reply. The environment I got the backtrace was on Ubuntu. As you kindly pointed out, my backtrace was without some dbgsym packages. After installing some *-dbgsym packages lacking, I get the backtrace again. The result is attached in this comment. I cannot find the appropriate dbgsym for uncovering ?? of "libQt3support.so.4." If you know it and let me know it, I will get the backtrace once again.
After this, I'm going to run and check tulip on Kubuntu and Debian unstable environments. Thank you again ! ** Attachment added: "backtrace result (no.2)" http://launchpadlibrarian.net/27313012/gdb-tulip-no2.txt -- tulip crashes on startup https://bugs.launchpad.net/bugs/230368 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
