Good evening Nicolas. I have, after a bit of a battle, downloaded 12.10 Alpha. I am having the same issue in 12.10 that I am having with 12.04. I purchased a Linux User magazine that had a 12.04 live cd (beta version) and tried it. I got the same error. I then tried the 11.10 live cd and also got the same error that I was getting in 12.04 and 12.10. I then tried the 11.04 live cd and I was able to connect to the internet.
This past weekend I went to my friend who also has an E220 modem and who is running 12.04 on one of his hard drives (he is also running 10.04). He is not experiencing connection issues. I tried my modem in his 12.04 and it would not connect. We then put his SIM card in my modem and it connected. I then tried my SIM card in his modem and it would not connect. I then put my cell phone's SIM card into both modems. Both did not connect. I have noticed that 10.04 is using modem-manager version 0.3. 11.04 is using modem-manager version 0.4. 11.10, 12.04 and 12.10 are using version 0.5. The error message popups in versions 11.10, 12.04 and 12.10 all complain under: SegvAnalysis Segfault happened at:0xb75ab3f0 <g_utf8_validate+464>: movzbl 0x0(%ebp),%eax PC(0xb75ab3f0)ok source "0x0(%ebp)" (0x00000000) not located in a known VMA region (needed readable region)! destination "%eax" ok SegvReason reading NULL VMA Nicolas what do you suggest I do next?

First, grab an iso of a daily cd of quantal and see if your modem works running the live session via booting from the cd. If so, then the newer versions of modem-manager and/or the kernel fix your issue. To try and see if the kernel fixes the issue, go ahead and try running the 12.10 kernel on 12.04. Instructions are here: http://www.theorangenotebook.com/2012/06/call-for-testing-1210-kernel- on-1204.html If a newer kernel doesn't work, you can try installing the newer version of modem-manager from quantal. If the livecd of quantal also fails, we can try using an older kernel and/or older version of modem-manager. Troubleshoot until you isolate the problem and then we can raise it to the applicable upstream. -- You received this bug notification because you are subscribed to the bug report. https://bugs.launchpad.net/bugs/1014054 Title: Huawei E220 modem will not connect in Ubuntu 12.04 Status in Ubuntu: New Bug description: Good afternoon my Huawei E220 USB modem will not connect in Ubuntu 12.04LTS. I connects in Ubuntu 9.04, 10.04LTS and Windows XP SP3. Every time I try and connect in 12.04 I get this error: modem-manager crashed with SIGSEGV in g_utf8_validate() I have searched the internet and I have been unable to find any information on what is causing this error message, and what to do to correct it. Because of this 12.04 is not usable.
